Subroutines for join/leave zone boilerplate & thief removal

Warzone now contains a few new methods to make adding and removing players from the zone easier. This was made in response to every join mechanism having to rewrite the same ~25 lines of code to handle adding players to a team. This was also done to replace the even more bulky code used to return stolen structures.

This also removes a few unused jobs as I am trying to transition away from them, as they don't really help if they are not being used for async tasks, batches, or timers.

A better way of managing teleports at the end of a game or when leaving normally has been added.
Configurable war zone max size

This war config option, MAXSIZE, can be used to change the limit on war zone size. Some reasons for using this could be to have a very long war zone or to limit the size from being abused by your zone makers. Thanks to @Delgado804 for the idea.
