[STABLE] UI Buttons, Particle Effects, and more

Added:
-8Bit font
-UIButtons
-Brick Particles
-Destructable tiles are now actually interactive
-Tiles are smarter
-Physics are reintroduced, however not to my liking (mostly the same,
still needs lots of tweaking)
-Level Timer has text
-UIOverlay smarter and handles button interactions

Changed:
-LifeCounter has become a generic Object Counter. This change will allow
a more diverse counting object to allow for counting coins, lives, and
other valuable information

Still in progress:
-Particle system for breaking bricks (Weird bug when adding an emitter;
x and y coords are off by way too much as you go farther out into the
level?)
