[gtranslator] Make the context information smarter.

[Ignacio Casal Quinteiro <icq src gnome org>]

commit b175293dcaa6a49c0a99eae52f5d5d34fd5d0974
Author: Ignacio Casal Quinteiro <icq gnome org>
Date:   Wed Apr 14 16:19:17 2010 +0200

    Make the context information smarter.
    
    Show only the header when there is info for that header and add
    a bold tag for the headers. Also sort the information in a more
    useful way.
