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<>.
virtual bool checkRTTI (const char *typenameStr)=0
 This function is only implemented by concrete classes and triggers the actual RTTI check through matchRTTI();.
bool matchRTTI (const char *typenameStr)
 Performs a check to see if the given typename string matches this class' This needs to be implemented in -all- subclasses, even abstract ones.
