[PATCH v6] emacs: Let the user choose where to compose new mails

Introduce a new defcustom notmuch-mua-compose-in that allows users to
specify where new mails are composed, either in the current window or
in a new window or frame.

Hi David et al.,

Here it is again, with a warning in the customize message that only
appears in Emacs 23. The indentation is a little bit of a mess but
that's needed for the docstring to look good :)

(If you want I can remove the test and also display the Emacs 23
warning in Emacs 24.)

Does it look good to you? I'm not comfortable with writing docs in
English, so feel free to rephrase it if needed.

I also moved notmuch-mua-compose-in to the 'notmuch-send group, just
as other notmuch-mua-* variables.

Regards,
Thomas
