Bukkit

Another attempt to fix at falling through the world.
Fixed dynmap support to delete the waypoints on /waypoints delete now.

When teleporting to a chunk that has not been loaded yet sometimes you will fall through the earth. Just retype /wps go <yourwaypoint> before you fall to far and you should be fine.

You may end up having to recreate some waypoints due to some code that ended up getting auto formatted in a earlier version that I did not catch, sorry for the inconvenience, waypoints locations may also not be correctly positioned in newer versions of craftbukkit as opposed to older versions for some reason.
