Updated the thread-ID navigation keys to be only ( and ) (I had added support for , and . to also work for that).  Updated to look for the configuration & theme config files in sbbs/mods first (and then in sbbs/ctrl, then the same directory as DDMsgReader.js, as before).

Renamed the reverseOrder configuration setting to reverseListOrder.  Added the enter key as a key to advance to the next message in reader mode.  Added the -subBoard command-line option, which can be used to specify a sub-board to read (by internal code or by number).  Fixed the msgReaderPath variable in DDScanMsgs.js and DDScanSubs.js to contain ../xtrn/DDMsgReader.  Updated the readme to reflect the change in the reverseListOrder configuration setting name, and also re-arranged the installation section of the readme.

Updated the logic for following a message's thread_back/thread_next & thread_id matching (using the ( and ) keys): Now first checks to see if thread_id is available (it checks to see if running Synchronet 3.16 and thread_id exists in the headers), and uses thread_id if available; if thread_id is not available, then it falls back on using the thread_back & thread_next fields.

Added by-title, by-author, and by to-user thread navigation as in Synchronet's stock message reader.  Also, added the ability to change to another message sub-board from the message list (using the C key).  Note that the ability to change to another sub-board is not enabled when doing a newscan or new-to-you message scan, since a scan is a more controlled flow.

Added scripts (and information in the Read Me file) for setting up Digital Distortion Message Reader in the new Loadable Modules options in SCFG > System > Loadable Modules.  This enables Digital Distortion Message Reader to be used, for instance, for reading personal email or doing a message newscan during the login process.

This is Digital Distortion Message Reader, which offers a scrollable reader interface for ANSI users (and falls back to a traditional interface for non-ANSI users).  Also supports searching & scanning (i.e., message newscan, new-to-you scan).  Additional features include built-in lightbar message list and message area chooser, as well as configurable colors and text strings.  This is still in beta but is fairly mature and stable.  The first official (non-beta) release will probably happen soon.
