workflow 4.7.x-1.0

With much fanfare, we are happy to release the first 4.7 official package of the workflow module. Until now, workflow users were required to grab snapshots from a constantly changing version of workflow. With this release, you can be confident that your copy of workflow will be available for later download, testing, bug reporting, and bug fixing. Hopefully, this more solid foundation will provide a good launching pad as we ratchet up for the 5.0 workflow release (and beyond!).
