small bugfix

-fixed debug console error messages
-fixed J toggle button taking several presses to work
-removed 'general' tab from config menu as it was unnecessary
-added 'fade out' option so text gradually disappears after introducing a new track
-added an optional check to display sountrack and track type even when custom title is not provided (mods without compatibility built-in)

Updated the music names for Repentance, better late than never I guess

Also, I tried the toggleable option and I don't know how to make it work without crashing, I'm not very well versed on Lua and how to mod for the mod config, I will keep trying but I don't promise anything
