Updated for SlyEdit version 1.52: Added a note about the new configuration file option, allowEditQuoteLines

Updated SlyEdit_ReadMe.txt for version 1.38.  Also updated SlyEdit_DD_Message_Lister_notes.txt to be more generic so I won't have to update it for a while.

SlyEdit version 1.33: Added a configuration option to set a text prefix for taglines.  The default is "... ".  Also added configuration options to shuffle (randomize) the taglines that are displayed to the user (set to true in SlyEdit.cfg) and to add double-quotes around taglines (defaults to false).  If the sysop wants to add double-quotes around taglines and not add a prefix to taglines, the prefix can be set to blank (nothing after the =).

SlyEdit version 1.32: Added the ability to choose a tagline to append to the message upon saving.  Also added user settings, which lets users configure whether or not they want to use taglines, whether or not to prepend the original author's intials to quoted lines, and whether or not to indent quoted lines that begin with author's initials.  Also made some misc. changes & bug fixes, such as:
- The maximum message name length in Ice mode is now 35 characters (up from 20 characters).
- The user's time left is now updated on the screen as it changes (checked & updated after each keypress).
- Bug fix: The time is now displayed in the correct location when the terminal is wider than 80 characters.
- Bug fix for DCT mode: Listing text replacements using Ctrl-T from the Help menu now works.
- Bug fix for DCT mode: Fixed an off-by-one bug for the horizontal position of the INS/OVR text when changing between insert & overwrite mode using a terminal size more than 80 characters wide.
- Some color setting name changes & addition in the color theme configuration files.

SlyEdit 1.29: Added a text replacement (AKA Macro) feature.  Added a new color setting, used when listing the text replacements: txtReplacementList.  Renamed the crossPostBorder and crossPostBorderTxt color settings to the more generic listBoxBorder and listBoxBorderText.  Also, did some code refactoring.  The new configuration file SlyEdit_TextReplacements.cfg are where the words & their replacements are defined for text replacements.  The new configuration option enableTextReplacements toggles whether or not to enable text replacements and has 3 values: false (disabled), true (enabled with literal text matching), and regex (enabled, using regular expressions).

Updated the SlyEdit documentation for v1.20.  Also added the SlyEdit upgrading notes file from the SlyEdit package, which contains important notes about upgrading from previous versions.
