Releases for Commerce (Product Display Manager)

This release is primarily bugfix release.

The only new feature added is an extra filter which allows one to filter on bundles of product display nodes when more then one bundle contains a product reference field. This feature was added after an bugfix/performance overhaul of the base query which generates the drag-and-drop overview list interface.
