As an editor I want to be able to edit all data that is shown to me in the Bridge.
We don't support editing of all values. We need to allow a bail-out to Wikidata for those cases so the editors can still edit this data.
GIVEN a statement with a special (somevalue or novalue) value
WHEN trying to edit it
THEN an message is shown leading the editor to edit on the repository instead
- trying to edit a statement with a special value (novalue of somevalue) results in a screen telling the editor to go to the repository
- hierarchy of bail-outs is datatype -> multiple values -> special value -> rank
