[PATCH] MIME: Output the filename of a part whatever the declared disposition.

[David Edmondson]

Some user agents create MIME parts that are generally not rendered
inline by the emacs user interface (for example application/pdf) yet
set the disposition for the part to 'inline'. If the user wishes to
save such parts it is convenient to be prompted with the filename used
for the attachment by the sender, should it be present. To allow this,
output the filename for all MIME parts if it is known irrespective of
the declared disposition.
