MyDial compatibility

From the begining of AtariST, many high level GEM programming libraries proposed their own custom objects using the userdef objects. The most famous library is perhaps the MyDial library. The ressource editor Interface uses MyDial to display news objects and it is really cool to see in the ressource editor what you'll see in your program. For that purpose, WinDom provides a set of predefined objects compatible with MyDial. MyDial can even be used instead of WinDom to display custom objects.
