Created a file lister (in JS) that lists files in the user's current file

directory with a lightbar interface, as well as message windows etc.

If the user does not have an ANSI terminal, this lister will run Synchronet's
stock file lister interface.

 It takes 2 parameters: An object of selected item indexes (as passed to GetVal()) and, optionally,
 the pre-calculated number of items.
 lbMenu.DoKeyDown(pNumItems, pSelectedItemIndexes);
+
+
+For screen refreshing, DDLightbarMenu includes the function DrawPartial(), which can be used to
+redraw only a portion of the menu, specified by starting X & Y coordinates, width, and height.
+The starting X & Y coordinates are relative to the upper-left corner of the menu (not absolute
+screen coordinates) and start at (1, 1).  The function signature looks like this:
+ DrawPartial(pStartX, pStartY, pWidth, pHeight, pSelectedItemIndexes)
+The parameters:
+ pStartX: The column of the character in the menu to start at
+ pStartY: The row of the character in the menu to start at
+ pWidth: The width of the content to draw
+ pHeight: The height of the content to draw
+ pSelectedItemIndexes: Optional - An object containing indexes of selected items
+
+Another function, DrawPartialAbs(), provies the same functionality but with absolute screen coordinates
+(also starting at (1, 1) in the upper-left corner):
+ DrawPartialAbs(pStartX, pStartY, pWidth, pHeight, pSelectedItemIndexes)
+The parameters:
+ pStartX: The column of the character in the menu to start at
+  pStartY: The row of the character in the menu to start at
+ pWidth: The width of the content to draw
+ pHeight: The height of the content to draw
+ pSelectedItemIndexes: Optional - An object containing indexes of selected items

+
+This file describes the Digital Distortion File Lister.
+
+Contents
+========
+1. Disclaimer
+2. Introduction
+3. Installation & Setup
+   - Command shell setup
+   - Background: Running JavaScript scripts in Synchronet
+4. Configuration file & color/text theme configuration file
+
+
+1. Disclaimer
+=============
+I cannot guarantee that this script is 100% free of bugs.  However, I have
+tested it, and I used it often during development, so I have some confidence
+that there are no serious issues with it (at least, none that I have seen).
+
+
+2. Introduction
+===============
+This release is version 2.00 because I had previously released a message lister
+mod for Synchronet which was just a list header and a command bar to display
+under the list, and it still used Synchronet's stock file list.  Now that
+Synchronet provides a JavaScript interface to its filebases (as of version
+3.19), more customization is possible with JavaScript.
+
+Digital Distortion File Lister is a script for Synchronet that provides an
+enhanced user interface (for ANSI terminals) for listing files in the user's
+current file directory.  This file lister uses a lightbar interface to list the
+files, a 'command bar' at the bottom of the screen allowing the user to use the
+left & right arrow keys or the first character of the action to select an
+action.  The file lister also uses message boxes to display information.
+
+If the user's terminal does not support ANSI, the file lister will run the
+stock Synchronet file lister interface instead.
+
+When adding files to the user's batch download queue or (for the sysop)
+selecting files to move or delete, multi-select mode can be used, allowing
+the user to select multiple files using the spacebar.  If the spacebar is not
+used, the file at the current highlighted lightbar location will be used.
+
+For viewing file information or viewining file contents, only the current file
+where the lightbar location will be used.
+
+For the lightbar file list, basic descriptions and short filenames are used in
+order for the information for each file to fit on a single line in the list.
+The user can view extended information for each file, in which case a window
+will be displayed with the filename, size, timestamp, and extended description.
+The file lister also provides the ability to view files (according to
+Synchronet's viewable files configuration), and adding files to the user's
+batch download queue.  Additionally, sysops can delete files and move files to
+another file directory.
+
+
+3. Installation & Setup
+=======================
+Aside from readme.txt revision_history.txt, Digital Distortion File Lister is
+comprised of the following files:
+
+1. ddfilelister.js        The Digital Distortion File Lister script
+
+2. ddfilelister.cfg       The file lister configuration file
+
+3. defaultTheme.cfg       The default theme file containing colors used in the
+                          file lister
+
+The configuration files are plain text files, so they can be edited using any
+editor.
+
+The .js script and .cfg files can be placed together in any directory.  When
+the lister reads the configuration file & theme file, the lister will first
+look in your sbbs/mods directory, then sbbs/ctrl, then in the same directory
+where the .js script is located.  So, if you desire, you could place
+ddfilelister.js in sbbs/exec and the .cfg file sin your sbbs/ctrl directory,
+for example.
+
+Command shell setup
+-------------------
+Running the file lister involves simply having the BBS run a command to run
+ddfilelister.js.  No command-line parameters are required.  The command to run
+ddfilelister.js can be placed in a command shell for a command key, or in
+SCFG > External Programs > Online Programs (Doors) in one of your program
+groups, and then you could have your command shell run the lister via the
+internal program code you configured in SCFG.
+
+Installing into a command shell is described in the subsection "Installing
+into a command shell".
+
+Background: Running JavaScript scripts in Synchronet
+----------------------------------------------------
+The command line to run this script would be as follows (if the script is in
+your sbbs/xtrn/ddfilelister directory):
+?../xtrn/ddfilelister/ddfilelister.js
+
+In a Baja script, you can use the 'exec' command to run a JavaScript script, as
+in the following example:
+exec "?../xtrn/ddfilelister/ddfilelister.js"
+
+In a JavaScript script, you can use the bbs.exec() function to run a JavaScript
+script, as in the following example:
+bbs.exec("?../xtrn/ddfilelister/ddfilelister.js");
+
+To install the file lister as an external program (in SCFG in External
+Programs > Online Programs (Doors)), see the following document for more
+information:
+http://wiki.synchro.net/howto:door:index?s[]=doors
+
+
+4. Configuration file & color/text theme configuration file
+===========================================================
+Digital Distortion File Lister allows changing some settings and colors via
+configuration files.  The configuration files are plain text and can be edited
+with any text editor.  These are the configuration files used by Digital
+Distortion File Lister:
+- ddfilelister.cfg: The main configuration file
+- defaultTheme.cfg: The default theme configuration file which defines colors
+  for items displayed in the file lister.  The name of this file can be
+  specified in ddfilelister.cfg, so that alternate "theme" configuration files
+  can be used if desired.
+
+Each setting in the configuration files has the format setting=value, where
+"setting" is the name of the setting or color, and "value" is the corresponding
+value to use.  The colors specified in the theme configuration file are
+Synchronet color/attribute codes.  Comments are allowed in the configuration
+files - Commented lines begin with a semicolon (;).
+
+Digital Distortion File Lister will look for the configuration files in the
+following directories, in the following order:
+1. sbbs/mods
+2. sbbs/ctrl
+3. The same directory as ddfilelister.js
+If you customize your configuration files, you can copy them to your sbbs/mods
+or sbbs/ctrl directory so that they'll be more difficutl to accidentally
+override if you update your xtrn/DDMsgReader from the Synchronet CVS
+repository, where this reader's files are checked in.
+
+The configuration settings are described in the sections below:
+
