Added a thin black border above and below the projections.

- solidify/style.h (PROJECTION_BORDER): number of pixels to leave dark above
  and below the face
- solidify/level.c (draw_xz, draw_zy, level): increase projection z size by
  twice the border width
- solidify/level.c (draw_xz, draw_zy): offset z coordinates by the border
