Initial Project Commit

This commit adds the game project and a slightly updated readme file.

Several things have been added to the game over the weekend. Vertical
and Horizontal Scrolling, Shooting Prototype, Draw Limits, New Sprites,
and Parallax Scrolling.

Next Step: refactoring Code to be more object oriented, adding keyboard
controls to gun functionality, changing gun functionality to aim at only
45 degree angles, control stick slow movement bug, enemy AI, Item class
for ammo pickups, etc...
