Safe texture compression (#2808)
Only a single program was used to safely compress all textures in MTG.

 * `optipng -o7 -zm1-9 -nc -strip all -clobber %%f`

The key command used is -nc, which stops color mode changes. I.e. any RGBA textures will remain RGBA textures, with none being changes to 8-bit indexed mode.

utils/optimize_textures.sh performs this compression automatically, assuming optipng is installed.

47efa2f558 Textures: Revert many back to RGBA to fix visual bug
With mip-mapping enabled, some GPUs cause a visual bug with indexed
textures that use alpha. This bug has been present for a while but
not noticed before. All indexed alpha textures must now be converted
to RGBA, to start this process we revert some textures converted to
indexed in the recent commit af3c918.

af3c91862c Convert many textures to indexed color
This fixes all cases where the color profile was broken, and
libpng warns about. It also makes almost all textures indexed
instead of RGB where possible (textures that don't have
semi-transparent pixels).
