This flag will show playbook output from non-failing commands. -v is also added to /usr/bin/ansible, but not yet used.
I also gutted some internals code dealing with 'invocations' which allowed the callback to know what module invoked
it. This is not something 0.5 does or needed, so callbacks have been simplified.
In playbooks, hosts can be a YAML list. We templated the list before
converting it to a semicolon-separated string, which actually templated its
repr. This converts to a string first. A basic unit test is included.
If we want to test playbooks, it's best to test the result of a playbook to make sure it does the correct thing. Also
remove playbook2/3 yml which were not used.
not being consistent between runs, even though there wasn't an error. Now we'll just check the final change
counts, which should be just as solid and lead to less churn in the events file.
refactoring of playbooks now warranted, which we'll do before we move on. This variable assignment
system makes nearly all possible magic possible, for we can use these variables however we like,
even as module names!
