* emacs/notmuch-show.el (notmuch-show-buttonized-link-colors):
new defcustom, allows toggling colorization of buttonized links.
* emacs/notmuch-show.el (notmuch-show-buttonized-link-present),
* emacs/notmuch-show.el (notmuch-show-buttonized-link-present-and-unread),
* emacs/notmuch-show.el (notmuch-show-buttonized-link-missing):
new faces for buttonized id: links.
* emacs/notmuch-show.el (notmuch-show-found-target-p): add optional arg
VERIFY-UNREAD which causes results to be filtered by "tag:unread".
* emacs/notmuch-show.el (notmuch-show-buttonize-links): use different
face property depending on the result of `notmuch-show-found-target-p',
causing buttons to available, available-and-unread and missing messages
to be displayed in a different color.
