Improved camera shake and added better Show No Mercy background!

Hey everyone! I uploaded a new PC build of Mythical Freaks earlier today. There are three new improvements in this build:

- The UI in the game looks better. I changed their size to be more dynamic.

- I improved the frequency of the camera shake. Previously, every time a character is damaged, it would shake. This has been reported to be a little to often. In this new build, the camera will only shake when a hurt sound is played, which happens randomly, but as frequently.

- I added a red background to all the stages except the training stage. This background will appear when the "Show No Mercy" sequence is triggered. It will disappear when the match ends. 

I'm hoping to have a Mac build with these improvements up and running later today (at the time of writing). In the meantime, if you're on Windows, feel free to try it out and leave some feedback. Happy gaming!
