workflow 7.x-2.0-beta1

Release 2.0 contains 2 major features:

1. Issue #2019345: A 'Workflow Field' is added, to allow workflow on any entity, leveraging Field API. The Workflow can also be changed from the comment form by adding the same field to the node type and its comment.
2. Lots of code is reshuffled into OO classes. Although this adds no new functionality, it reduces duplicate code and facilitates a future upgrade to Drupal 8.

For module builders, this introduced some incompatibilities with the previous version 7.x-1.2. Please see the change records.

Furthermore, lots of issues have been resolved. All changes are listed in CHANGELOG.txt. Below is a list of highlighted commits:
