Glass 3.0(BETA 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 crashes

Update information:
===
v0.3.0
Version Nickname: Crystal-Clear
*Added Okay Glass feature, which works a lot
^like the real Glass.
*Removed Garbage Collectors and defined
^variables as local when needed instead, as
^suggested by TheOriginalBit
*Added mPrint(text,line,color) which is like
^tinyPrint but fits 10 lines
*Added tinyCPrint(text,line,color) which is
^just like the normal tinyPrint but is
^centered. Also done with
^mCPrint(text,line,color)!
*Improved how tinyPrint works
*Fixed the PixelAPI to display pixels at the
^right coords.
*Added drawLineX(startx, endx,y,color,trans)
^and drawLineY(starty,endy,x,color,trans)
^which basicly draw lines
*Added sleepmode, which can be turned on by
^doing $$sleep on the home screen.
*Added reboot, which can be done by doing
^$$reboot at the home screen
*Added options, which includes an updater :D
*Added Books. Books go in CCGBooks/ and need
^no sepcial format whatsoever. Just text.
*Removed bookPrint(an empty function)
*Added to the versioning system more
*Removed Herobrine

===
v0.2.1: Fixes the glitch where the terminal
would always need to be on the left side, no
matter what
Adds pixelClear(), 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
