 - added default multipage_filetype (PDF).
   No default multipage_filetype produced the following problem:
   - error message when creating multipage file: could not create secure file

 - lineart images are expanded to grayscale in multipage mode.
   solves segmentation fault when "show page" in multipage project was \ 
selected

 - corrected calculation of width and height in copy mode for backends
   that do not support arbitary resolutions

 - multipage mode: lineart images (that are stored as grayscale images)
   are reduced to lineart before the page is put into the multipage file

 - viewer shows image info with bit depth = 1 when reduce_to_lineart is set

 - change handling of zoom (photocopy mode):
   - now there is only one zoom value even if there is a resolution_x and
     a resolution_y option, zoom_x and zoom_y are removed
   - the zoom factor is directly used to define the image output size
     (before the scanresolution was used to define the image output size)
   - the resolution is not changed any more when an other printer with a
     different printer resolution is selected
