Misc warnings

- Removed/Commented some unused vars
- CValue::GetPropertyText() could return a temp reference to a variable on the stack, option wasnt used anywhere so removed.
- KX_ConstraintWrapper::GetConstraintId allows args but ignored them
- KX_ConstraintWrapper::PySetParam didnt return NULL on an error (messing up pythons exceptions).
- BLI_natstrcmp didnt return 0 when the while loop exited
