Subject: [PATCH] [IMP] Add action for choosing a variant as the price
 reference

- This can be very handy for the website if we want to use not the cheapest variant as the default
  displayed price. It also reorders the attribute values such that when opening a product on the
  website, it immediately shows the reference variant.
