Fix update of a Word file from MS Office through a WebDAV drive

The initial problem was that the document version was not incremented when a MS Office file was edited.
After some investigation, we discover that the current document is put to trash and a new document is created with the changes. This is the consequence of this WebDAV flow:

1. PUT /newpath.tmp : create a new temporary document in Nuxeo
2. MOVE /current.doc /anotherpath.tmp : move the current document to another path
3. MOVE /newpath.tmp /current.doc : move the temporary document to the document which was initially edited => it actually only change the
4. DELETE /anotherpath.tmp

We need to find a way to push the updated blob to the initial document.

And after an update, the document version should be incremented, as it happens with documents edited with Notepad or Paint.
