[Corey Berla <coreyberla src gnome org>]

commit 0d426bd23431e8d7f2c79e494b97b5ba08d14b1d
Author: Corey Berla <corey berla me>

    app-chooser: Add property single-mime-type
    
    If we are acting on a single item or multiple items that all have the
    same mime type, set to true. This will be used for setting the title
    and ability to change file type association.
