Now uses a file to list ais, and has one ai.jar

Ant is committing horrors upon every build.
Great success.

Also changed the ai loading code so it loads from that file.
Merge branch 'master' into build

Conflicts:
	PlayerAI/build.xml
	game/src/gameEngine/GameEngine.java
	game/src/launcher/LauncherWindow.java

Also, fixed .classpath missing from game/
