Map file

This is a simple version of a map file that has general settings and a few locations. I suggest reviewing all code, but the main changes are in the map.py file.

To test this:
1. Run bitfl.py
2. N for new game
3. A for add player
4. Type any name
5. S to start game
6. M to move player

This will display a grid of the map, where you should see an h and a b for home and bank on the grid.
