ROUGH DRAFT

Here is the very first running version of the game! Lots of stuff
doesn't work yet, especially with the zombie controller. Also, no XML
yet. The values are just hard coded. To run the game, you need to change
the file paths that are located in Background.java, Firetrap.java,
Obstacle.java, Player.java, and Zombie.java. The images are located in
zombiehouse/graphics/resources
