Decorations over IMVU rooms: the hub's side

T5 products placed in ordinary IMVU rooms, kept per room instance
(room_decoration, migration 0006). GET /api/v1/decorations/:instance (and
?instances= for up to 20) gives what the viewer may see, with a hash;
PUT is for the room owner's T5DE person only, checks the products exist,
and tells every realtime session with a chat in that room ({"type":
"decor"}). Hosted rooms' IDs are refused.
