feat(tools/emacs): Bindings for (un)collapsing notmuch subthreads

Browse source 
Modifies notmuch-show-open-or-close-subthread to take a parameter
instead of using prefix to toggle the argument, and binds that
function to C-, and C-. in notmuch-show-mode-map to enable convenient
collapsing/uncollapsing of subthreads from point.
