Don't call owl_list_create in owl_dict_get_keys Until we get rid of this owl_list thing altogether, there should be a convention as to who initializes the thing. Otherwise, we leak memory from people initializing it too many times. Whoever reviews this probably wants to look over this very carefully in case I missed one of the owl_list_creates. Also kill the various wrappers over owl_list_cleanup as they are not the inverse of any operation.
