1. In the player move event we looped through the jailed players more
than once which really is an issue when you have several hundred jailed
and since the move event is called several times a second, that was a
huge performance hit.
2. Don't save the prisoner data as soon as they are jailed, we take care
of that else where with the shutting down and counting down time.
I want to get fully away from blocking methods and instead make the
user/player/prisoner/whatever wait to get an answer while we retrieve
the uuid information asynchronously.
