Commerce Commerce 1.x Upgrades v1.10

Rename FreeProducts module to AutoProducts

As you can now also use the FreeProducts module to add products with a price to an order, we renamed it to AutoProducts. Users will not be able to remove such products, making it useful for things like mandatory charges.

In rare cases where this module was extended this may cause a backwards compatibility break, however we don’t recommend doing that to begin with.
