As an editor I want to be able to edit all data that is shown to me in the Bridge.
**Problem:**
We don't support editing of all values and references and cases. We need to allow a bail-out to Wikidata for those cases so the editors can still edit this data.
**Example:**
* the snak contains a no-value/some-value value
* deprecated values
**Screenshots/mockups:**
Deprecated value
{F31512087}
unknown/Some value
{F31512089}
No value
{F31512091}
**BDD**
GIVEN a statement with a deprecated value
WHEN trying to edit it
THEN an message is shown leading the editor to edit on the repository instead
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
**Acceptance criteria:**
[ ] trying to edit a statement with a deprecated value results in a screen telling the editor to go to the repository
[ ] trying to edit a statement with a special value (novalue of somevalue) results in a screen telling the editor to go to the repository
**Open questions:**
* hierarchy of bail-outs (datatype -> multiple values -> special value -> rank ?)
