Glass V0.2.1

--[[
If you're wanting to make an application for
CCGlass, please read the guide on the forums.
Every time a developer doesn't read the guide,
an innocent computer dies

Update information:
===
v0.2.1: Fixes the glitch where the terminal
would always need to be on the left side, no
matter what.
Adds pixeClear(), which clears the pixels on
the pixelAPI.
Redid the versioning system to a more popular
way of versioning applications.
===
v0.2.0: Adds the Pixel API, aswell as the
"Garbage Collectors" that set variables
that are no longer needed at the ends of funct-
ions to nil.
===
v0.1.0
Initial Release
