Brecht Van Lommel 112385660a RNA 
* Object has some more properties wrapped, mostly game related.
* Scene frame changes now send a notifier.
* Added functions to create/free operator properties for calling
  operators. This also simplifies some duplicated code that did
  this. Ideally though this kind of thing should use the properties
  pointer provided by buttons and keymap items. Example code:

PointerRNA ptr;

WM_operator_properties_create(&ptr, "SOME_OT_name");
RNA_int_set(&ptr, "value", 42);
WM_operator_name_call(C, "SOME_OT_name", WM_OP_EXEC_DEFAULT, &ptr);
WM_operator_properties_free(&ptr);
