Separating mac modeler code

[Andrus Adamchik]

Just realized that when running Modeler from Eclipse on Mac, I have a  
bunch of functions absent from the menu, due to this code in  
CayenneModelerFrame.java:

      // Mac OS X doesn't use File->Exit, it uses CayenneModeler- 
>Quit (command-Q)
       if (!SystemUtils.IS_OS_MAC_OSX) {
           fileMenu.addSeparator();
            
fileMenu.add(getAction(ExitAction.getActionName()).buildMenu());
       }
       // Mac OS X has it's own Preferences menu item under the  
application menu
       if (!SystemUtils.IS_OS_MAC_OSX) {
           toolMenu.addSeparator();
            
toolMenu 
.add(getAction(ConfigurePreferencesAction.getActionName()).buildMenu());
       }

       // Mac OS X "About CayenneModeler" appears under the  
application menu, per Apple GUI standards
       if (!SystemUtils.IS_OS_MAC_OSX)
            
helpMenu.add(getAction(AboutAction.getActionName()).buildMenu());


It would be nice if we could refactor this code to move all Mac  
specific logic into the "modeler/cayenne-modeler-mac-ext" module...  
(not only to make it runnable from Eclipse, but also to separate  
platform-specific logic from the modeler core). Anybody wants to look  
at this?

Thanks
