GHex Migrated to gnome-doc-utils

[Rodney Dawes <dobey pwns gmail com>]

Hi everyone,

I've just committed the changes to ghex to migrate the documentation to
using gnome-doc-utils. Please, if you can, updated the existing XML
files and png images in figures/ to align with the latest screen shot
recommendations for GNOME documentation. And please make sure the
translations are up to date as well. All of the translated versions are
out of date with the untranslated version.

See http://bugzilla.gnome.org/show_bug.cgi?id=333819

It would be great if we could get this fixed up for 2.20.

Thanks to Claude for helping on IRC, and everyone.
