Bug Fixes and new Pause Menu

Thank you to dr!ppy for giving me some bugs that I didn't see. I was able to remove the issue when you keep upgrading a unit it would take your resources. The flurry axemen not attacking should be fixed as well. I couldn't reproduce the bard or mage issue so hopefully it was a weird issue.

I also have put a pause menu in, clicking escape will bring it up. You will no longer see that bright pink window anymore. There is also some random tips inside the pause menu. If you have any good tip idea please send them over.

That's it, Happy Sunday.
