First Real update

I have now updated the game in a significant way I have overhauled the enemies and wave system, as well as a number of balance changes.  I also added the ability to toggle fullscreen  with CTRL.

Most of the changes are behind the hood though and will allow for an easier time with future updates.

Next update will be a big one. I plan on improving the menus and adding some more effects. Also I have Ideas on a new boss and extra enemies.
