    bin/meld: Fix missing translations for GTK-loaded resources (#321)
    
    Moving to having template widgets broke translation for those widgets,
    because we moved from loading via GtkBuilder with explicit domains from
    Python to loading with the domains set in the C library. We'd done
    *almost* all the work to bind those, but for some reason hadn't
    correctly set `textdomain`.
    
    The Windows libintl change here is purely theoretical; translations
    don't work on Windows in the current build, so we can't even test
    whether this does the right thing.
