Bad textures persist steam uninstall [Unclean uninstall]

[mmetully]

Been diagnosing purple asteroids issue, deleted game using steam uninstall, unsubscribed form all mods, deleted mod cache, loaded game on SSP, played with settings.

I just found that uninstalling the game did not remove all files used by the game after a reinstall. These voxel textures originally created 2014 were found in the game files.

Summary of files remaining after uninstall
