Colorize Game Tables in Lobby for different statuses

[bocaben]

Colorize Game Tables in Lobby for different statuses, such that they are shaded a different color for each of {waiting, running, finished}.

Isn't the "Room#: " enough for this?

To clarify, I meant something like: Waiting tables should be tinted green Running tables tinted yellow Finished tables tinted red (traffic light colors for example, actual colors could be decided)

I started working on this in PR #206.
