Reworked EarlyDisplay Texturing

[shartte]

EarlyDisplay currently binds all its textures to the GL state at the same time. It essentially uses multi-texturing texturing units as "storage" for its texture handles.
This PR changes that so that only texturing unit 0 is used, and EarlyDisplay keeps track of the GL texture ids normally.
What it does NOT fix yet is the fact that EarlyDisplay never actually deletes the textures it creates.
