Singleton cleanup

The SmUberModel class wasn't needed at all, so I removed it.

Instead I renamed SmUmberModelSingleton into a real singleton
for all QAbstractItemModel*, though right now it only supports
the SeriesTreeModel and FileTreeModel. But it should eventually
evolve into a singleton for all QAbstractItemModel *. For this
I renamed the class SmUberModelSingleton to SmModelSingleton.
