Version 1.0.2

I've added lots of things to this update. There is now a high score, gets harder, sound effects, and a little better music. One issue that i'm still working on is the high score, it takes one point off your actual high score (Ex: high score of 5 will = high score of 4). The sound effects and music might be a little too much in the end but that's an easy fix.  What i really wanted to do was make the zombies go faster like waves, although there aren't waves, they do get faster over time (every 5 seconds). I still have lots to go with Zombie Annihilator, but I'll get there
