- Rename .chat-body to .chatroom-body
- Upate SASS for chat rooms
- Hide the room occupants view by toggling the class "hidden"
- The chatroom chat area and occupants list are now shown as table cells.

- Width needs to be set on .chatroom obj as well.

- Make sure initDragResize gets called (in .show())
- Handle case (which shouldn't happen and is hopefully now fixed) when min_height is not set.

Text area of chat boxes don't yet resize properly.
Didn't test at all on chat rooms.
