    i18n: use itstool to extract strings from the glade catalog
    
    In our case, the titles don't need to be translated, since they contain
    class names (e.g. "GtkSourceView"). So only the names of properties
    values are translated.
    
    Glade doesn't support '_name' attributes, it must be 'name'. With the
    ITS rules the strings are correctly extracted, but in the xml file it's
    less clear what is translated. Maybe a better solution is to run a sed
    command to rename _name -> name. Or an even better solution is to
    support _name attributes in glade, like we do for .lang files and style
    schemes in GtkSourceView.
