Arcade game background change

I added a new background for my game
Alien missiles changed

I changed the aliens missile spawn so it made the game a little easier.
Deleted fonts

I only needed one font so I deleted the others and made it so that it
was available on any machine.
Images for background and controls

I added a few new images to test out which look best.
Description of game and alien spawn points

I changed the number and spawn points of my aliens and also added a
description of the game at the top of the page.
