[svn] Apply patch from Jan De Luyck. Add new option 'add-messageid-if-missing', which optionally postpones adding a message ID to the upstream server. If this is done, post-locally must be off. This is to deal with an upstream server troubling Jan. It usually (but not always) rejects posts with a Noffle message ID. I have changed Jan's original option of 'add-message-id-if-missing' for consistency with 'replace-messageid' and added the manual page entry. See SourceForge feature request 1513395.
