Subject: [PATCH] Expose to the world the document archiving functions: -
 loading: slightly edited the loading function to call the right open function
 of Document in case the file is a document archive (choosen normally in the
 "open" dialog) - saving: added an entry in the "export to" formats (and
 shuffled some code for being more flexible)

probably not much ideal for an usability POV, but we can work on it.
