Java Space Invaders

After making Pong I was looking for something a little more challenging to play around with. I had been considering Space Invaders for some time, but thought that it would probably be too difficult to be worth it, however after coming up with nothing else I decided to give it a try. Most of it was quite simple, however the bases a bit more work - and still aren't what I'd like them to be. There is still some functionality (such as levelling, sounds, and explosion images) that I'd like to add, but at the moment everything's there.
