_noshaders PNG Option

[wheels1758]

It seems that since terrain shaders were implemented, people want to use them almost exclusively. Typically they will look better than static shading on terrain decals, which is fine. However, it seems people don't always check/care what they look like without shaders, which ends up with blotchy textures and funny shading. Would it be possible to add a "_noshader.png" which would only show up when shaders are off and allow static shading for people not running terrain shaders?

Looks like it'd be pretty simple to change. The only part that'd be a little messy would be saving in the editor when the _noshader file is in use since the editor would thing that was the primary texture in that case.
