Less Lispy

I have massively reduced the number of parenthesis in the code. I started using the C# built-in getters/setters and it's really made the code easier to read despite that I was avoiding them for just that reason. Collisions are still not perfect, and I'm tempted to add new sprites for a third and fourth player and maybe it set it up so it'd be possible, but I'm running out of official time to work on it. It's pretty good timing, but I wish I had a little more to work on that the giant leap it'd require to add more players. Also the controls would be difficult to figure out. Still, the code looks nicer now.
