Performance overhaul sponsored by rockxz3, using his large server's data for reference to help with testing and tuning. Timing numbers below are based on this data set.

Browse Source 
* PlayerMoveEvent performance boost (from 0.047ms to 0.015ms in testing, ~313% as fast): now more thrifty in determining whether player has actually moved between chunks before doing anything else; important since this event triggers extremely quickly
* PlayerInteractEvent performance boost (from 0.068ms to 0.034ms in testing, ~200% as fast): now ignores left-clicks for interaction checks, since in CraftBukkit 1.4 left-clicks no longer open doors or activate buttons/levers/etc.; not as important as above, but still triggers quite often as people are digging or interacting with blocks
* "/f list" command performance boost (from 234ms to 30ms in testing, ~780% as fast): code was getting information for all factions, narrowed it down to only getting info for displayed page range
* "/f show" command performance boost (from 132ms to 28ms in testing, ~470% as fast): tweaked the ally & enemy listing code used
