Handle clicks on "cid" URLs by popping up a "Save Attachment" dialog.
* mail-display.c (on_link_clicked): Handle clicks on "cid" URLs by popping up a "Save Attachment" dialog. * mail-format.c (get_cid): if the part has a Content-Disposition with a filename specified, record (a sanitized version of) that on the wrapper when creating the cid reference, so the "save attachment" code can use it later. (handle_mystery): fix a bug in the cid generation here. svn path=/trunk/; revision=2685
