ULTRAPONG V1.2

We here at the ULTRAPONG team strive for quality. We are proud to announce that ULTRAPONG is officially 100% bug free and available on Linux. 

CHANGES:

> The game will now run on Ubuntu systems, although the file must be given permission to run by the user.

> The window is no longer resizable. This has been done specifically to spite ultra-wide screens and because higher resolutions mess with the game.

> The game's only major bug (if the ball hit a paddle from below, it would take the paddle with it) has been patched. Anything else you see is a feature
