RFK testing

The program which will eventually become rfk 1.40 is here, and the source is here. I would like some people to playtest it. Changes:

• you can move around by tapping parts of the screen, rather than tapping with respect to robot's position; this is more like the iPhone port (which I haven't played); this change suggested by Will Thompson
• portrait mode
• kitten is on the front screen

I would like to know

• whether portrait mode is playable, in general
• whether it would make more sense to spin the board around 90° instead of pivoting it in place
• whether there are too few spaces on one axis to make it easily playable in portrait mode
• why the GtkLabel with the message on it on the front screen does not expand to the full height of the window in portrait mode (I'm sure I'm missing something obvious here)
• whether you think a picture like this one would be better for the front page
• anything else you find

Thanks for your help, everyone who is helping.
