E-mail notifications moved into Conditional Actions

In Ubercart 1.x, there was a core notifications module that handled sending checkout notification e-mails to customers and administrators and order update e-mails to customers. This functionality was taken from a specific module and moved into the Conditional Actions system. By default, Ubercart comes with predicates that handle these notifications. Because e-mails are now handled through CA, you have greater control over when and how e-mails will be sent out and what they will contain. To update your checkout notification settings, edit the appropriate predicates at Administer > Store administration > Conditional actions.
