AW_fnc_baseVehSpawn needs to return object created and base created at

[Jack Williams]

Because AW_fnc_baseVehSpawn is an FSM, it doesn't return any proper variables as it's just using execFSM. What execFSM does give us, however, is the FSM ID. With that, we can just grab a variable from the completed .fsm using getFSMVariable.

I only realised this after I went to bed last night.
