Plan for 0.6 release -- feature freeze Wednesday, testing now, release Monday (approx)

The plan for 0.6's release is as follows:

* everyone pound on modules as much as you can, the new "common code" stuff might have made some of them have subtle bugs I'd like to get ironed out
* I'll work on upgrading playbook test code so we can thoroughly exercise all the variables/other features in the tests
* feature freeze this Wednesday -- pull requests for non-bugs will be held until next Monday (approximately)
* plan on release next Monday (approximately) after any bugs found as a result of testing are fixed
