Deep watch for vortoProperty directive
By adding  to the  call in the vortoProperty directive, we ensure that angular will watch value changes recursively. This fixes a bug with some property editors that have a json structure (in my case it was Archetype, but there are many others).
The bug was that after saving a document, further changes were ignored until the document was reloaded.
