GCCPY:
	* Bug fix on empty return statements
	* Added list.append ()
	* Added support for runtime to add method attributes
	  to types via:
"""
static struct gpy_builtinAttribs_t list_methods[] = {
  /* 2 arguments since we have to pass in self, append_item */
  { "append", 2, (GPY_CFUNC) &gpy_obj_list_append },
  /* ... */
  { NULL, 0, NULL }
};
"""

Then on initilization of type: call gpy_wrap_builtins ()
