Implemented static paths for mobs (like Don Doom and Bad Max).

* Mobs now retreat to where they were when they were roaming; not their
spawn point
* /toggleai still sends them back to their spawn point however
* Fixed a bug where mobs would respawn where they were killed instead of
their proper spawn point
* Fixed mobs roaming despite simulatemobs being set to false
* Updated tdata submodule
