Database schema change and new UI feature. The user can now rearrange the products.

* Product has a new 'order' column.
* The user can now specify the sort order at product creation time with the
  'product add --sort INT' command.
* The user can now rearrange the products with the 'products set --sort INT'
  comand.
* The user can now show a sorted list of products in cli.py with the
  'product list --sort' command.
