Bukkit

• More attempts to fix flying issues. When a lift is generated it will now check to see if the player is still in a current lift.
• PreventLeave is now defaulted to true in new installs.

Longer version: I just realized the issue. To prevent the kick for flying issue Lift activates flying for all players. It maintains a list of players who can fly before they entered the lift, and disables flying for players not on the lift aftr the lift ends. When players activate the second lift their "canFly" flag is still set to true, so they are added to the list of players who should still be flying.

The preventLeave config option and the new code I added should be a fix. If players still found a way to keep flying I have a couple more ideas on how to solve it.
