- fixed a conversion warning with the pointer-type AActor fields.

Browse source 
- added master and tracer to the list of exported variables.
- fixed: 'none' as class type must map to the real null pointer so that it won't get rejected by the stricter type checks.
- added handling for member function calls to zcc_compile.cpp.
- fixed: FxMemberFunctionCall may not delete the self expression if it gets passed on to the actual function call.
