craig.p.drummond 229f555367 Hack around issues with QObject, multiple inheritance, and static_cast of void pointer. 
Moc requires QObject to be the fist when using multiple inheriteance, but the model uses void pointers and we want to cast up/down the music heirarchy.
Therefore, when MOC is run use QOvject as the first item. But when actually compiled use MusicLibraryItemRoot
