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.
The name property is supposed to be already a displayable string,
without any further work.
Also, that gettext call wouldn't have any effect, since we don't
have those strings in our catalogs.
