gnome-user-docs translations

[Shaun McCance <shaunm gnome org>]

Hi folks,

gnome-user-docs isn't listed on l10n.gnome.org. This module
has one Mallard document to translate: gnome-help. It used
to contain three DocBook documents, and we had translations
for those, so I assume it used to be listed.

The document isn't finished yet. We'll be doing a lot of work
on it at a hackfest in mid-March.

Thanks,
Shaun
