Bug 1087041 - Return the list of rooms with status.

We now have a new getRoomInfo function which can get you the room information,
and are using it in the GET /rooms/:token and GET /rooms endpoints so we are
sure they return the same fields.

ok. It's a poor naming but I guess the API is settled now.
