(svn r12880) [NoAI] -Add: introduces ai_types.hpp, which has all NNNId like VehicleID. This simplifies the include-mess, and avoids including tons of _type.h for just a single typedef.
-Note: this is perfectly safe; when a type changes, any sane compiler starts complaining about redefining the typedef to an other type
