Add allegrogl 0.2.0,

The library mostly provides functions to allow you to use
OpenGL alongside Allegro -- you use OpenGL for your rendering
to the screen, and Allegro for miscellaneous tasks like
gathering input, doing timers, getting cross-platform
portability, loading data, playing samples and drawing your
textures. So this library fills the same hole that things like
GLUT do.
