RTTI replacement
Note A note on why the RTTI replacement is needed: RTTI calls fail once the object crosses the dso boundary. We revert to using simple string checks which is more expensive but at least works once the dso is used in Houdini, etc. Use field_dynamic_cast<> for any RefBase subclass instead of dynamic_cast<>.
