Scoring system!

Rheum now has a few more layers (of flesh) in the scoring system. While the system isn't revolutionary or all that deep, I think it adds a nice incentive to play different if you're into beating your high scores! There's a few ways to get extra points:

• Killing enemies up close
• Not using your rheum meter. Get more points but less upgrades/hp/bombs, which makes the game harder if it isn't doing it for you!
• Using your bombs at moments when the screen is mostly bullets.

And now your high scores are saved! They'll display in the options menu, and they correspond to the currently selected game mode/difficulty. 

Other then that, I fixed a few graphical issues and instances where text wouldn't fit on the screen. I think. I hope.

Eye go bye bye now!
