Lighting now talks directly to CraftBukkit and is now approximately 115 times faster. Yep.
Because lighting has gone from taking up 92% of processing time to a trivial amount, the plugin no longer
splits lighting/generating/saving into separate steps.
Because lighting is now very fast, /lighting is now the default. It can still be disabled with /lighting:none
/lighting:extreme is now named /lighting:force, and only eats a little bit more CPU.
Added /destroyAndRegenerateArea - which regenerates all chunks in the region. Beware!
Removed /lightExisting, lighting is now only done as-needed either way, and /lighting:force can be used
to try and fix corrupt light areas.
Fixed /gencircle being centered incorrectly when called by a player without coordinates
Improved accuracy of some fuzzy math logic to ensure only requested areas are generated
Added /onlyWhenEmpty - this causes the plugin to only do its work when the server is empty, pausing and resuming
as needed when players join/leave.
Minor speed/overhead improvements
Recent builds of CraftBukkit will eat up a lot of ram on big generations on /fast and /veryfast modes.
I have proposed a fix for this bug here, but until the Bukkit team
addresses this, users with lower ram limitations may wish to use /slow modes or consider applying that patch.
