[BUG?] Issues in recent doc switch for gnome-panel

[Luca Ferretti <elle uca libero it>]

I'm porting Italian user's guide in gnome-panel package to recently
switched gnome-doc-utils. There are 3 issues:

     1. Figures are not installed. See the console log[1] for clock. In
        Makefile there are those entries[2], but no DOC_FIGURES is
        declared. So I suppose it depends on some Makefile.am missing,
        but I did't explore it deeply.
     2. The fish applet code claims for "fish-applet-2.xml", while now
        the document's name is "fish.xml" (applet popup menu and Help
        button in Preferences dialog).
     3. Value in document header (<article id="index" lang="../xx/xx">)
        should be simply lang="xx". But this could be an issue of my
        system: I'm updating the gnome-doc-utils translation too, and it
        seems that intltool-update generates a wrong it.po (and POT)
        file here[3], so maybe this could be related.


PS I'm not on gnome-doc-list :-P

i.e. this entry (note the missing form='x')

        msgid "<msgstr>Author</msgstr> <msgstr>Authors</msgstr>"

and this (note the missing role='x')
