Missed a mention of Java 5. We build for Java 6, as per the Minecraft spec.
Clear attributes on death; mistranslation issue.
Return inGround when checking Arrow's OnGround state. Fixes BUKKIT-4439
Correctly fire VehicleExitEvent. Fixes BUKKIT-3761

This change makes it so that EntityHuman#setPassengerOf(Entity) invokes
its parent method when leaving vehicles so that VehicleExitEvent is fired
for players leaving vehicles.

This change also fixes BUKKIT-2110, making it so VehicleExitEvent
correctly handles cancellation. The implementation of VehicleExitEvent
completely ignored the cancellation state of the event, making it so that
cancelling the event had no effect.  Cancelling a VehicleExitEvent now
causes the entity to remain inside of the vehicle, with no visual stutter.
