[PATCH] contrib: add notmuch-emacs-mailto.sh

[Tomi Ollila]

Add a shell handler which sends to/invokes notmuch-emacs mua
mailto: urls for further processing.
---

I wish notmuch-mua-mailto (not (yet) in notmuch improves as
"promised" in id:87vcin2fo6.fsf at servo.finestructure.net ;D
(that version seems to do more than implementation of
browse-url-mail (in emacs-23.1/lisp/net/browse-url.el) and
with that buffer is not marked "modified" when some initial
body added).
