compatibility with emacs22
Emacs22 lacks apply-partially and mouse-event-p, so define them if emacs version is less than 23. With this change, I was able to begin using notmuch in emacs22. The definitions of apply-partially and mouse-event-p are copied from the emacs 23 distribution, (which is distributed under the GPLv3+ just as notmuch).
