It is not used anymore, now that translations are bundled with
the extension. Also, in the zip files it ended up with my home
folder, which is not nice.
Cherry-picked from master, added code to load translation from
within the extension folder.
Introduce a translation domain, gnome-shell-extensions, and use it
in extensions that have user-facing strings, instead of abusing
of translations provided by gnome-shell.
Also includes an example translation for italian, and bump the
required version for xrandr-indicator.
Depends on GNOME bug 621017.
