added dimension_default global to provide default dimensions. expected to be a (var) constant.
support setcustomskin in menuqc.
implement some considerations for win95, so it can actually run on that horrendously outdated system.
provide scr_autoid and r_showbbox-field info when running csqc.
ignore vid_restarts at the end of config.cfg files from other engines. in fte, these are at best redundant and at worst overrides user settings.
fix issue with latched cvars not flagging the config as modified.
path command always shows filenames properly.
fix some fteqcc inlining bugs.
added precaches command to display all active precaches.
added docs for mapcluster.
