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. git-svn-id: https://svn.eduke32.com/eduke32@3761 1a8010ca-5511-0410-912e-c29ae57300e0
