/**
* Replace a version of a document
*
* Each document may have any number of content elements attached to it.
* This function replaces the file content of a given version.
* Using this function is highly discourage, because it undermines the
* idea of keeping all versions of a document as originally saved.
* Content will only be replaced if the mimetype, filetype, user and
* original filename are identical to the version being updated.
*
* This function was introduced for the webdav server because any saving
* of a document created a new version.
