JKA shader are just about complete.

I moved all shader references into their proper shader file(s).
Created new shader files where needed.
Removed shader files that were not needed.

Considering not including the "GFX" shader file since it doesn't have any 
references to mapping stuff.

Would also like to move "radiant" textures and "system" textures into 
the "common" folder to condense the folder listing in the drop down menu.
