/* This is a script that lets the user choose a message area,
* with either a lightbar or traditional user interface.
*
* Date User Version Description
* 2010-02-05 Eric Oulashin 0.90 Started
* 2010-02-18 to
* 2010-02-27 Eric Oulashin Continued work.
* Added the first & lasg page functionality
* to the lightbar interface.
* 2010-03-13 Eric Oulashin 1.00 Added the ability to load settings from a
* configuration file.
* 2011-04-22 Eric Oulashin 1.01 Fixed the wording when choosing a message
* group - It now says "group #" instead
* of "sub-board #".
* 2012-10-06 Eric Oulashin 1.02 For lightbar mode, updated to display the
* page number in the header at the top (in
* addition to the total number of pages,
* which it was already displaying).
* 2012-11-30 Eric Oulashin 1.03 Bug fix: After leaving the help screen
* from the sub-board list, the top line is
* now correctly written with the page
* information as "Page # of #".
* 2013-05-04 Eric Oulashin 1.04 Updated to dynamically adjust the length
* of the # messages column based on the
* greatest number of messages of all
* sub-boards within a message group so
* that the formatting still looks good.
* 2013-05-10 Eric Oulashin 1.05 Updated the version to match the
* version in DDFileAreaChooser (a bug
* was fixed there, but DDMsgAreaChooser
* didn't have the corresponding bug).
* 2014-09-14 Eric Oulashin 1.06 Bug fix: Updated the highlight (lightbar)
* format string in the
* DDMsgAreaChooser_buildSubBoardPrintfInfoForGrp()
* function to include a normal attribute at
* the end to avoid color issues when clearing
* the screen, etc. Bug reported by Psi-Jack.
* 2014-12-22 Eric Oulashin 1.07 Bug fix: Made this.colors.subBoardHeader apply
* to the whole line rather than just the page
* number.
* Bug fix: The initial display of the page number
* is now correct (previously, it would start out
* saying page 1, even if on another page).
* 2015-04-19 Eric Oulashin 1.08 Added color settings for the lightbar help text
* at the bottom of the screen. Also, added the
* ability to use the PageUp & PageDown keys instead
* of P and N in the lightbar lists.
* 2016-01-17 Eric Oulashin 1.09 Updated to allow choosing only the sub-board within
* the user's current message group. The first command-
* line argument now specifies whether or not to
* allow choosing the message group, and it defaults
* to true.
* 2016-02-12 Eric Oulashin 1.10Beta Started working on adding the ability to display
* a header ANSI/ASCII file above the list.
* 2016-02-15 Eric Oulashin 1.10 Releasing this version
* 2016-02-19 Eric Oulashin 1.11 Bug fix: The page number wasn't being updated
* when changing pages in the message groups
* when using the arrow keys to scroll between
* pages
* 2016-11-20 Eric Oulashin 1.12 Started working on updating to handle null
* message headers, which could happen with the
* new voting feature in Synchronet 3.17.
* 2016-11-22 Eric Oulashin 1.12 Releasing this version
* 2016-12-11 Eric Oulashin 1.13 Updated to show the number of readable messages rather than
* the actual total number of messages in the sub-boards (in
* case some messages are deleted, unverified, etc.)
