BGE API Cleanup: update the python attribute definition framework.

Browse Source 
* Value clamping to min/max is now supported as an option for integer, float 
  and string attribute (for string clamping=trim to max length)
* Post check function now take PyAttributeDef parameter so that more 
  generic function can be written.
* Definition of SCA_ILogicBrick::CheckProperty() function to check that
  a string attribute contains a valid property name of the parent game object.
* Definition of enum attribute vi KX_PYATTRIBUTE_ENUM... macros. 
  Enum are handled just like integer but to be totally paranoid, the sizeof()
  of the enum member is check at run time to match integer size.
* More bricks updated to use the framework.
