New part output handling as option to notmuch-show.
Outputting of single MIME parts is moved to an option of notmuch show, instead of being handled in it's own sub-command. The recent rework of multipart mime allowed for this change but consolidating part handling into a single recursive function (show_message_part) that includes formatting. This allows for far simpler handling single output of a single part, including formatting.
