Added mini-map

There is now a mini map that shows your room as well as the rooms beside you. It also tells you if it's a red room. There is one exception, the secret portal. Since the secret portal leads to a random location in the map, the red room detection goes into no-snitch mode.

For those of you who don't know about the secret portal, it doesn't exist. There's totally no secret portal that has a small chance of sending you to a demon room that inevitably kills you...
