#969 Make Polylines, Dimensions, Rooms and Walls groupable

[Twonky]

With version 6.1.2, only furniture objects can be added to a group.

I would love to be able to create groups of / containing polylines, dimensions, rooms and walls as well.

[Emmanuel Puybaret]

Not sure it will happen. First, it's less required than for furniture (if needed, don't forget you may use multiple selection and/or isolate some items in levels at same eleveation), and the furniture list displays only... furniture, so I don't see how groups containing furniture and items of another kind could behave in the list.

[Matyáš Pilz]

I think that groups of one kind of items will be very useful (group of rooms, group of walls...).
