Cleaned up z0 plane input/output. Note: need to change fx in all .sfy files !

Browse Source 
- solidify/face.h (fx_to_angle, fy_to_angle, fx_from_angle, fy_from_angle):
  helper functions to get/set the z0 plane inclination
- solidify/povray.c (povray_face), solidify/project.c (read_face_data,
  save_face_data): use helper functions to get/set z0 plane
- solidify/project.c (read_face_data, save_face_data): don't negate fx
