Changing a bunch of stuff.
- Started working on the basketball game.
- It uses a bow ball.
- The ball should remain on the field. (Untested)
- Made a start with making toString() methods to be able to save games.
	- There are probably loops (Goal has a team, the team has a goal,
								creates a loop of text)
A listener for the bowball.
- When a player shoots a bow, it is checked if he is currently in a
basketballgame.
- If he is, then the bow will shoot a snowball instead of an arrow.
- The snowball should bounce off objects and exist forever (might cause
terrible lagg for colliding constantly with the block).
- If the snowball bounces outside of the field, it should get destroyed
