[Albrecht Dreß <albrecht src gnome org>]

commit 63f626bdb14314f2112a53aa2fbe041e279b3510
Author: Albrecht Dreß <albrecht dress netcologne de>
Date:   Fri Jan 21 21:18:17 2022 +0100

    add ability to open download location after download
    
    See issue #66.
    
    Add an additional context menu option for opening the file manager with
    the enclosing folder after saving an attachment.
    
    Details:
    - src/balsa-message: iff a default app info for 'inode/directory' is
    available, add a 'Save and view' context menu item with the app info
    - src/balsa-mime-widget-callbacks.[ch]: iff saving the file was
    successful and an app info has been passed, launch it with the folder
