Fixed /acmds string concatenation bug
Moved rules to settings.json

Rules are now loaded from the settings.json file as an array.

Rules aren't displayed as a dialog any more, to allow players to
continue running around/playing/etc while they read them instead of
being stuck with a dialog on screen.

Updated the settings.json file (overdue) with various new settings that
have been added and deleted the old settings.cfg file (no idea why it
was still there)

Fixed a small bug in settings auto-generation, the gTotalInfoMessage
wasn't set to 3 despite 3 default info-messages being set.
