Enable multiplayer

If you want to play our entry against another player then this is possible (this went unmentioned in the readme.txt):

Just un-comment following lines in context_game.py (line 54 and following):

        # # add other players
        # # arrows
        # canoe = Canoe(timing.Timer(scheduler=self.scheduler))
        # canoe.position.y += 150 / PPU
        # self.canoes.append(canoe)  # uncomment for second player

The second player uses the arrow keys instead of a s d f. Same position of key does the same, but you figure that out.

There is no special treatment for multiple player, so the level will just end when the first arrives at the end.

Have fun racing the levels.
