Close or open The Hanger online

This functionality allows you to prevent purchasing of all Hanger products, and re-enable later. You can also show a message to explain why the shop is closed, provide date(s), or provide a contact address.

If the shop is closed, products are still published (or left unpublished if they are unpublished). However they cannot be added to the cart, and the message shows if users try to.

1. Union menu -> Shop -> Shop settings (including e-mails)
2. Check or uncheck the checkbox "The Hanger online shop is open"
   1. If it is checked, products are available if published.
   2. If it is not checked, products are still published but not available for purchase.
3. Enter a message on "Message shown on shop and products when closed." to explain what's going on.
4. Go to the end and click "Save".
