Options Page + Score Update + Sounds

I made some changes, though that was prolly obvious.

- Bullets no longer take away from your score. I felt that it was a bit unfair since it already takes away from your health which I plan on making a randomly spawning pickup for soon. 
- I added sounds. Things now go pewpew and shazam. And my personal favorite, bonk.
- There is officially an options page that I totally programmed and didn't just use for a little easter egg because I don't know how to code it.
