Remove all Mordor shaders to set up for better fix.

These were preliminary, and it's cleaner to start fresh in this folder as a staging ground for Mike's latest drop.

We can always get the older shaders via git anyway.

This avoids some bizarreness with it thinking shaders were renamed, when they were in fact deleted.
Add all of Mike's latest Mordor shader fixes 11-9-14.

Big update to clean up shaders.
Includes some manually fixed shaders.
Remove the export_binary option from d3dx.ini.

This would generate .bin files for every shader seen, and is something that doesn't seem to make sense. We never used this feature, and I'm unsure when I would ever use this, or why.
Especially because there is already a cache_shaders option which does that for active shaders, but not every one seen.

This change is part of making ShaderCache just an archive, and not live.
Fix bug in BeforeDraw that would disable texture and shader overrides.

This was overlooked during hunting=1 work, and accidentally disabled the override feature when hunting=0.
