* 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);
