Title: Tri Shield Powerup

This version of the scrolling shooter has the tri shield added in. A few points of interest:
-For the bitmask, I expect everyone to be fighting over 0x2, so I just took 0x128.
-I took the 'draw the sprite's representation on-screen' literally. Since there wasn't a list of powerups in the game class, I added one myself. Let me know if I need to take that back.
-Since there's no collision yet, I've refrained from allowing the player to actually acquire the upgrade for now.

Things should be commented on well enough. Let me know if something more needs to be done.
