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.
