Added OGL windows
 -When you specify a color in main, it'll pop up an OGL window showing what your color looks like. The program shouldn't continue until you close that window.

Changed colorparser
 -Now interpolates between multiple colors if you enter them (e.g. blue green comes out sorta cyany)
 -Warning, this is subtractive so if you add too many colors you'll end up with brown or black a lot, don't combine more than 2 or 3 colors.
