Bukkit

• enabled gworld-commands (except "warpto") to be used from the console
• added support for SuperPerms
• implemented dynamic world loading - on startup only your default world(s) will get loaded. Any other world will be loaded as soon as a player tries to access that world and will be unloaded when no player is active in that world for 5min. Disabled by default. This can be enabled/tweaked in the config.yml Please be aware of this bug when playing around with this feature.
• added /gworld load
• added /gworld unload
• added /gworld setsticky (controls if a world will be automatically loaded/unloaded with dynamic world loading enabled)
• added /gworld keepspawninmemory
• implemented custom chunkgenerators (referred to as additional "environments") - currently available: flatlands, island, hillvalley
• implemented getDefaultChunkGenerator(), enabling craftbukkit to use the custom ChunkGenerators for your default world(s)

in your bukkit.yml:

   worlds:
       worldname:
           generator: XcraftGate:FLATLANDS
   

• added /gworld listenv - shows available environments
• new worlds now obey the pvp-setting in server.properties
