Subject: Issue a warning if a document has two parents. We should do something smart then... 
X-Git-Tag: 2.0.0~5254

Issue a warning if a document has two parents. We should do something smart then, but what?

- Do we want to ask the user which of the parents he would like to be the document's parent ?
- Do we want to disable any functionality related to parents ? Like references, bibliography, document outline etc.
