Update graphics/feh to 1.2.7.

Changes:

  * Require giblib 1.2.4 now.
  * Applied large patch from Claes Nasten <pekdon@pekdon.net>
  * Several tweaks to thumbnail.c including support for the "Thumbnail
    Managing Standard" described at freedesktop.org. Thumbnails are cached in
    a way which makes them accessible to other programs, under ~/.thumbnails
    using md5sum filenames.
  * He had to invoke libpng directly to write out the comments/tags required
    by the spec, but that seems to be a trend with feh now so what the hell :p
  * Nice patch from JC <jcm314@yahoo.com>
  * Alongside the original --action option, adds --action1 through --action9,
    allowing you to define multiple actions which can be run using the number
    keys. Lets you set up a list of commands for organising images.
  * New method for rotating jpegs - does a lossless jpeg rotation (thanks,
    IJG) and preserves EXIF data, as requested by many users :)
  * Fix minor documentation omissions (debian bug reports)
  * Various warning fixes from Claes Nasten <pekdon@pekdon.net>
  * Support full X geometry flags
  * removed extraneous XFlush
  * switched to global file list length (avoid recalculating it
    constantly)
