Get rid of that old model occlusion checking hack I wrote for Polymost years ago. I actually didn't know this was still in EDuke32... it's one of the worst things I've ever written. :p

Add an experimental shading mode to Polymost for .art tiles, in which extra textures are allocated for each shade level based on the classic mode shade tables. Enable with r_usetileshades 1 (disabled by default). This uses a lot of memory and is still very WIP (a lot of the shading is completely wrong at this point).

Also, further refactor texcache code.
