These patches implement a reply to sender function.
On the command line this is done via a new format
"--format=one" to notmuch reply.
In emacs it is bound to the key R

I have been running a similar patch set for some time but 
only tidied it up today. It compiles and works for me.

This is my first submission to the project so I hope that I
have done everything right.
