bbs.load_text() can now be used to load text*.ini file

For sysops that don't want to use the user's chosen language to auto-load
alternate text strings, they can specify some other filename from the ctrl
directory (so long as it ends in .ini). I wouldn't use text.*.ini however,
since those filenames are assumed to be language translations and will
automatically appear in user_settings.js as a user-selectable language.
text-*.ini would be fine though as an alternate text.ini filename:
not colliding with text.ini or text.*.ini
