notmuch.el: Handle attached images via an external viewer.

Browse source 
We temporarily override the mm-inline-media-tests variable so that the
only parts inserted into the temporary buffer (and lost) are those
parts that the user has already seen in the notmuch-show buffer.

Anything else, (such as images), will now be left to be handled via
mailcap, just like other attachment types.
