... a lot of stuff

-there's a boss now
-you can shoot the boss(no animation)
-you can win the game now
-changed the platforms
-you can toggle the platform letters with p
-"o" makes the boss activate (for testing)
-the laser now shoots randomly at all platforms
-spacebar from the win screen restarts the game

KNOWN PROBLEMS:
-platforms need to be resized(too small)
-laser is still insta-kill
-can't toggle platform letters during boss fight
-needs more diversity
