Space Invaders Example - Including Additions From Lab5

Addition to the Windows build, this includes the tasks we had in lab no. 5 in the Programming Project module. I quite liked the additions in this one that is why I decided to publish it as a separate version.

Same note: I have done zero consideration to reduce the file size, as this is an example and not a stand-alone game. Perhaps I'll try to shrink its size in the future. Enjoy the game.
