New Version - Different health and better pathfinding

Uploaded a new version of the game today.

I have changed the way the health works. It now maxes out at 100%. I found that I was able to get 300-400 health early on which took away some of the later challenge of 5 zombies.

I have also created far better path finding for the enemies. No longer will they get stuck behind barriers! They are still a little predictable, but that will soon change too no doubt!
