Image reading, template handling, and printing bug fixes.

CHANGES:
    - Add fl_read_image() note and move documentation STRs back
      to the top of the list...

fluid/fluid.cxx:
    - Use printer choice data instead of the label text, since
      we have to escape / in printer names.
    - Change page number in header to n/N.

fluid/print_panel.*:
    - Don't disable properties button, ever.
    - Quote / in printer names.
    - Put copy of real printer name in the user data.
    - Use user data instead of label text for printer name.

fluid/template_panel.*:
    - Only free the files array if num_files > 0.

src/fl_read_image.cxx:
    - Use fl_visual->visual->*_mask instead of fl_*mask and
      fl_*shift when the XGetImage() data does not have them
      set.
