Support Display Folders for Table Objects

I can understand the idea that ideally the average model really shouldn't have so many tables that you require folders and this might just encourage some bad practices, however there are clearly some good use cases for table folders. * Info.view related documentation would be much nicer in their own folder. * unconnected tables, for variables, field parameters, calculation groups really should be groupable and separate from the 'real' data Even fairly simple models could easily have 15+ tables if they implement a fairly small number of these, that is before you get to the really large multi-fact models that exist.
