Further bot improvements

Browse source 
* Player-requested structures are properly integrated into the base system to prevent duplicates and better anticipate player desires
* Improved bot path finding for moving targets, hopefully they get caught less often on railings and stuff when pursuing a moving target
* When bots teleport (e.g. phase gate, but any kind of teleport), they clear their stored unstuck locations so they don't try and backtrack when attempting to get unstuck
