- added constraint type identifiers and marked the old ones as deprecated (still valid): PH_SPHERICAL for PH_BALL, PH_REVOLUTE for PH_HINGE, PH_CYLINDRICAL for PH_SLIDER and PH_DISTANCE for PH_ROPE
- added constraint types for (yet unsupported): PH_FIXED, PH_POINTINPLANE, PH_POINTONLINE, PH_PULLEY (commented in the Lite-C header; available internally)
- added internal DLL function pXconGetJointData to remove overhead for joint functions; will reduce code in the future
- added internal DLL function int pXconGetType (ENTITY* e, int* refType) to retrieve constraint type in DLL scope (int); supports the unsupported constraints also (upward compatibility!)
- added external DLL function var pXconGetType (ENTITY* e), which returns the constraint type in Lite-C scope (var)
