Message:In POV-Ray output, move faces to more correct Z locations.

- solidify/povray.c: update title for renaming
- solidify/povray.c (povray_face, povray): flip the bottom face
- solidify/povray.c (povray_face, povray): instead of centering the face on
Z, shift it to its z0 position
- solidify/povray.c (povray_face, povray): split the distance between faces
equally among them
