Offer invitations in room creation

Turns the "Create Room" form into a tabbed form with
tabs that mimic the room display. In the "Members" tab
an AutocompleteArrayInput allows selecting multiple
users by their displayname.

The displayname is also what is displayed ìn the
invitations list.

Creating the room immediately sends out the invitations
as well.
