commerce 7.x-1.0-alpha4

The last week has seen a flurry of activity that accounts for about half of the commits for the last 6 weeks. This is due in large part to the great number of patches contributed from other developers, giving me plenty to review and build on. This release contains more solid Entity / Rules / Views integration and an improved shopping cart workflow. It also contains my first uses of EntityFieldQuery and the Entity Metadata Wrapper, two critical APIs for building Fieldable Entity based systems. Once again all our SimpleTests pass, too, though we're still in need of a lot more.

The pièce de résistance of alpha 3 was the dynamic Add to Cart form, which has seen bug fixes in this release to address inconsistencies in the dependent attribute display. I'm not sure if I can top the awesomeness of that form in this release, but the Rules powered dynamic pricing system at least comes close.

It is now possible to create Rules on the Calculating the sell price of a product event that can adjust the sell price as necessary, providing a central system and user interface for discount systems, tax calculation and display, and multi-currency stores. At the same time, a price pre-calculation system has been developed at the database and API level (user interface pending) that populates the commerce_calculated_price table in the database with dynamic price data for use in queries for things like Views and faceted searches.
