[notmuch] [PATCH] compatibility with emacs22

[James Vasile]

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.

apply-partially cribbed from http://notmuchmail.org/pipermail/notmuch/2009/000889.html

This is an updated patch that fixes a bug in the last version.
