[PATCH] [RFC] emacs: merge overhauled `notmuch-cycle-notmuch-buffers' into `notmuch'

[Pieter Praet]

CLisp'ier version of `notmuch-cycle-notmuch-buffers', merged into `notmuch',
eliminating the need to hog yet another keybind.

FYI: causes 2 compile warnings due to requiring the cl package at runtime.
