[PATCH] emacs: add pipe attachment command

[Mark Walters]

Allow the user to pipe the attachment somewhere. Bound to '|' on the
attachment button.

I found myself missing this functionality. It uses mm-pipe-part which
is nice as it sends single line output to the minibuffer and multiline
output to a new emacs buffer.
