Improve the builtin vs bonobo selection code. (handle_mystery): Include
* mail-format.c (lookup_handler, etc): Improve the builtin vs bonobo selection code. (handle_mystery): Include name and Content-Description in the "mystery data" info, when available (handle_unknown_type): Call mail_identify_mime_part before giving up. (handle_undisplayable): Split out of handle_unknown_type now that handle_unknown_type can try alternate viewers. (handle_via_bonobo): Fall back to handle_undisplayable if the bonobo control fails. * mail-identify.c (mail_identify_mime_part): New function to attempt to identify a MIME part that we can't identify based on Content-Type alone. * mail-display.c (on_url_requested): redo the mystery data icon display stuff less kludgily. svn path=/trunk/; revision=2684
