Bukkit

This is actually build against craftbukkit 1.7.5 but that was not a selectable option when uploading the plugin..

This is a major update. A lot of the code has changed.

 - Speeded up raw terrain generation
 - Added a scheduler for terrain rendering tasks which should make terrain generation less heavy on the server
 - Now stores all rendering tasks in the queue to disk on /reload or /stop
 - Makes sure the chunk generator is properly reloaded after a /reload (circumvents craftbukkit chunk generator bug)
 - Added ice spikes of packed ice
 - Replaced a lot of the snow layer with packed ice
 - Can now properly rotate more blocks in schematics
 - new /hothpaste command for pasting schematics manually into the world
 - new /hothlist command for listing all internal and loaded external schematics
 - new /hothundo command for undoing /hothpaste commands
 - Added lots of 1.7 items to loot lists
 - Packed ice now drops blocks
 - Added hard clay to clay layer
 - Isolated use of deprecated bukkit functions while waiting for replacement functions

Untested against anything below craftbukkit 1.7.5.

Dome rendering still takes a lot of time so you might experience server lag while domes are being rendered.
