Instead of the Fly Map, the Soar Map!

Using a simple flying map is so 2003. Let's update things with a mode7 soaring map. Someone has made this already, here:

Make sure we test every landing on every possible route, or disabling said landing on a route. If the route lands us in the water somewhere, we may have to make a spawn point for us to land at instead, so we land on land.

Also, remove the barrel rolls and the Lati@s sprite, and put in a generic bird sprite. This is replacing Fly, not adding Soar.

Also, it would be nice if the land below wasn't obviously the town map.
