Bukkit

+ Some code cleanup
+ measure serverside lag in a seperate thread, once every 20 ticks
+ (Server) lag resistant "more packets" check, will deactivate itself temporarily if lag > 0.5 seconds to avoid false positives
+ minor adjustments to default config settings
+ fixed a bug that would deactivate the durability check if the morepackets check got deactivated (c+p mistake)

- New "more packets" check may let more hacks slip through, especially if the server is under high load
