[p4-feedback] P4 and OWL 1

I've implemented this as a refactor action.
This gives the user more flexibility as you can transform existing
ontologies (so obviously if a plugin doesn't do the "correct" thing for your
circumstances it is still possible to transform).
Will be available in the next build (next week with any luck).

> The quickest solution I can put in place is an option on the "Make all
> primitive siblings disjoint" action.
> But at some point it would be really nice to have "save as owl1.0" which
> performs transforms where possible and warns where not.
