Bug fixes + source code drop!

So, it's been a while huh?

Why am I suddenly updating a two-year-old project? Because I recently submitted it as part of my university's game design showcase! And, well, a few of the bugs would really get in the way of people being able to play it. So I went back, found my old stashed source code (good thing I saved those!) and fixed a few of the more glaring bugs. This update is focused on gamepad support.

Also, I've released the full source code on my github: https://github.com/AhoyGamers/SideBlaster. This does not give anybody permission to reupload the game or take it as their own. At the very least, please credit me if you use any scripts from the project.

Fixes:
-Can now move to the settings menu and change values with only a controller.
-Can now connect a controller on the shape choosing screen and it will allow player to select a shape with the recent controller.
-Fixed freezing when pausing the game and returning to main menu.
-Pause screen now fits the aesthetic of the game, and shows a clearer indicator which button is selected with controller.
-Added linux build
