Added scaling to basteroids

Changes:
* views/game/zacman_include_v.php ~ Fixed styling on gui so that it
doesn't glitch when the window is resized.
* js/games/basteroids/css/game.css ~ Cleaned up the style a bit so that
its easier to change canvas size. Also fixed styling on gui so that it
doesn't glitch when the window is resized.
* js/games/basteroids/scripts/...
* views/game/basteroids_game_v.php
~ Basteroids can now be scaled to any canvas width. This was needed as
its original width was uncomfortably big for embedding into the page.
