OpenGL2: Fix black planar projection shadows (cg_shadows 3)

Browse source 
Restore MD3 code for cg_shadows 2 and 3 like other model formats.
Fix planar projection shadow deform (cg_shadows 3) to use correct
light direction. I fixed light direction for stencil shadows
(cg_shadows 2) but it's still broken.
