Unable to compile, problem with classes derived from ash.core.System

[alexmarchenko]

Hello.

I have cloned whole repo, but was unable to find bundled Ash, so I cloned latest version from repo and copied it to src folder.

Unable to compile Asteroids due to problem with the systems inheritance. At the prepare method of net.richardlord.asteroids.Asteroids, where the new systems are constructed and added to the engine, constructors of GameManager, GunControlSystem, BulletAgeSystem, MovementSystem and CollisionSystem all have some parameters passed to them. Yet neither derived classes, nor ash.core.System class have constructor defined.
