Merge pull request #8 from PurdueSIGGD/Level-Change

Level change is now added. 
-Levels now change to another level 5 seconds after every enemy is killed. Current order is Example_map Example_mapandersed -> Level_1
-Every level map must include "nextLevel" name to be initiated to the gamemode. If your jimmies are rustled, pull up a chair (or a pillow) and let me explain. Otherwise, just deal with it.
-Also fixed some incorrect timer uses. 
-It says I messed with some things, but all I did was open them, no worries
Happy coding
