Sounds and a boss

I added a few sounds in certain actions. I think I am going to change all of them, but I have the programming set up to easily change the sounds out. 

More importantly, I added a bossfight. I was going to be more ambitious with this, but it was fun for me to try to beat it with just the simple animation it has playing. The only issue so far is that it doesn't look like it's trying to fight you. (although it definitely is)
