More updated menus

Working more on getting the round over and game over menus looking a lot more clean and have some useful information. I also fixed a bug with the upgrade menus not centering. Now when the game ends it will show you how many people you let die...sorry but you didn't defend them. The round over menu will go over how much experience you earned. I want to try and think of something else to put on here but can't think of anything at the moment.
