FC038: Default action is allowed, refs #154.

Previously we were only using #allowed_actions to determine which
actions were valid for a resource. This broke for the log resource which
doesn't specify :write as an allowed_action.
Add metadata for Chef 11.6.0.

We need to filter out the WindowsScript resource as it can't be
instantiated only with name. That should be ok as I think it's just a
superclass for the new powershell and batch resources.
