The add contact form.

- Remove currently unused pure modules (forms and menus)
- Update forms (not all yet) markup and css
- Move all controlbox mockups to mockup/controlbox.html

Forms look much better now in mockups but JS and templates still needs updating.

- All chats (boxes and rooms) should now have .chatbox class (for base styles)
- Move specific stuff to new sass files (fonts, chatbox, normalize)

Wouldn't mind getting rid of grunt completely.

- 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.
- Update docs on allow_dragresize to mention that min-width and min-height
  values are honored.

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

when it comes to chat box resizing.

Only leftward resizing is allowed since there's no space for boxes to expand on the right.
Text area of chat boxes don't yet resize properly.
Didn't test at all on chat rooms.
