First pass at support for slope-implied walls. Doesn't work in all cases, but works better.
Tile info display is working! I have no idea why walls aren't always working.
Detect walls where a slope means that the floor and ceiling of the tile touch along one edge
Walls finally work now
Move kinetic.js into top level, and delete old maps - the new ones are too large to check in, so they're being moved to separate hosting
Add a simple README
remove some stray debugging code
