Add lots of debug output and a user-viewable log of it

Make another chat window that the user can switch on (with a debug-enabled exe).
Should probably keep a rolling log in a file, since it'll get lengthy/memory intensive (maybe).

Should help diagnose #92 and maybe #90, #89, #80, #81, #82, #30, #41, #42

[debug logging] Logging all over the place. It's insane! (If you actually can fish, and view it--debug compile only)
fixes #96 -- people should download debug EXE if they're interested.
