David Edmondson 45ad21fba1 emacs: Re-arrange message sending code
Define a new `mail-user-agent' (`notmuch-user-agent') and use it by
default. Re-arrange various routines that send mail to use this
(compose, reply, forward). Insert a `User-Agent:' header by default.

This is the real commit for this functionality this time. The
previous attempt to merge this code:

	commit 57926bc7b0

was botched (by Carl Worth, not David) to include only the Makefile
change. So the build was broken until this commit that actually adds
the new file.
