[PATCH v2 5/6] emacs: add support for reversing notmuch-search-archive-thread tag changes

[Jani Nikula <jani@nikula.org>]

Since archiving a thread can now be a user customized set of tag
changes, make reversing this easier. Allow a prefix argument to
notmuch-search-archive-thread to reverse the archiving, similar to the
unarchiving in notmuch-show-archive-message.
