Added new log mechanism. More simpler and easier to use.

added a new macro named gdx_log, and exposed the log variable as an item on the gdx namespace. This is useful if you want to bypass the
macro system and do logs on release.

Changed the way GL variables are defined.

Since the seldom usage of GL parameters from the native GL/gl.h includes is not good at all, and
manually setting them is ugly, I've decided to create a pseudo namespace "GL" (to avoid namespace classhing
with opengl defines) inside gdx so we can access these variables from outside. Internally we can use the include inside internal/gl that
exports the native callbacks.

Also, I've made GLES to be the default driver on Linux (hope that all bugs are gone now).
Removed more fields that were not part of GLES
Added a getVolume method for the Music class
