0.0.2 - Navigation

Made a basic map screen with enterable towns and dungeons. Click on
town/dungeon icons to enter, click on Back button to go back to map.
There's nothing in these yet except for fantastic graphics - I'm just
trying to get the basic infrastructure of the game functioning before I
make any actual game, since I don't want to be coming up with tons of
ideas and puzzles and then be unable to even make a game engine.
