ubercart 5.x-1.0-alpha8

Ubercart Alpha 8 brings many new core features to the table, including file downloads, user role promotions, and Workflow-ng integration. Other features have been enhanced or tweaked, and the usual stream of bugfixes have been applied. It feels like cheating to call this a minor release from Alpha 7e, but all these changes have made it in over the last few weeks. Plenty of credit goes to our newest active developer, Shawn, who was able to spring board off the efforts of community developers aymerick, CpILL, torgosPizza, and others.
