* debian/ghostscript-cups.ppd-updater: Added data file to trigger the update of the PPD files of existing print queues by CUPS and to tell CUPS which PPD files to use for the update and how to match them with the PPDs of the existing queues. * debian/ghostscript-cups.postinst: Removed the post-install script which was only there to update the PPDs of existing print queues. * debian/rules: Install ghostscript-cups.ppd-updater and remove the dependency on cups-client from ghostscript-cups. * debian/patches/1000_fix_segfaults_in_cups_raster_device.patch: Temporary fix for segfaults in the CUPS Raster output device. It stops the segfaults but has a slight memory leak. A better fix is in the works by the upstream developers.
