Methods
Called when this extension is added to a particular class
Temporarily modify the owner. The original owner is ensured to be restored
Clear the current owner, and restore extension to the state prior to the last setOwner()
Helper method to strip eval'ed arguments from a string that's passed to DataObject::$extensions or Object::add_extension().
Auto-append current stage if we're in draft, to avoid relying on session state for this, and the related potential of showing draft content without varying the URL itself.

This should also pull through to form actions.
