BGE PyAPI fixes

- CValue warning ShowDeprecationWarning("val = ob.attr", "val = ob['attr']"); had false positives because of python using getattr() internally. Only show the wanring now when a CValue is found.
- Py functions that accepted a vector and a GameObject were slowed down by PySequence_Check() first called on the GameObject, though this would fail it would try and get attributes from the game object - ending up in ~8 attribute lookups each time. Avoiding PySequence_Check() makes ob.getDistanceTo(otherOb) over twice as fast.

- Joystick hat events could crash the BGE for joysticks with more then 4 hats.
- PLY Import failed on PLY files from Carve, added some extra types.
