Correct ship velocity bug
Initial fork from my Asteroids base
Change to l/r/u/d directions; no rotation
Fixing movement responsiveness
Correct vertical out-of-bounds (no more vertical wrap)
Debug Asteroid#correctOutOfBounds for vertical bound
Debug Asteroid#correctOutOfBounds for vertical bound
Speed up base Asteroid velocity
Resize screen
Add Star.js and stars to black background
Display moving stars and wrap them correctly
Create Powerups of various colors
Make powerups appear on destroy Asteroid; next handle collisions and gain powers
Refactor Game#move for DRYness
Refactor Game#checkCollisions into different methods
Refactor Game#checkAsteroidCollisions; begin Game#checkShipCollisions
Implement Ship#gainPowerup and various helper methods
Refactor Ship#fireBullet to handle powerups
Firing multiple bullets; for some reason have crazy richochet bullets; cool
