- use own OrderedDictMini class, pythons collections.OrderedDict is overkill, 179 sloc. replaced with own, 11 lines. - remove code which stored the class file & line per RNA subclass, this was useful but would raise its own exception every time to generate a stack trace to get the class info so we could use of the class failed to register. the class stores its module & name which can be enough to find where it was defined.
