The ordering of entries jumps around sometimes when reading from
Transifex (this might be Python unordered dictionaries, or based
on translation statistics -- I can't tell). Force an order by
sorting on language code and key-name so they all end up grouped
by language code, sorted Name Icon GenericName Comment.
Although this shuffles some more entries now, longer-term it
will reduce churn in the .desktop file.
