Release 1.6.1 - now with new roomgfx, mazemode!

This release has new gfx, now drawn in code, not predrawn ( thansk mspaint) gifs. Like 'em or hate 'em, pretty similar anyway.
Also a wholly new feature is mazemode, click it on and once you have used all the exits in a room, the room will be colored differently so you can see where you have been already.

As a bugfix, changing the roomcolors should stick now, no longer reset on its own.
