[notmuch] [PATCH -v4] notmuch.el: Add face support to search and show mode

This add two faces, notmuch-show-subject-face and
notmuch-tag-face. The first face is used to show the subject
line in the notmuch-show-mode and the second one to show tags
in the notmuch-search-mode.

We can selectively highlight each tag by setting notmuch-tag-face-alist as below

(defface notmuch-tag-unread-face
 '((((class color) (background light)) (:foreground "goldenrod" :bold t))
    (((class color) (background dark)) (:foreground "goldenrod" :bold t)))
  "Notmuch search mode face used to highligh tags.")

(defface notmuch-tag-inbox-face
 '((((class color) (background light)) (:foreground "red" :bold t))
    (((class color) (background dark)) (:foreground "red" :bold t)))
  "Notmuch search mode face used to highligh tags.")

(setq notmuch-tag-face-alist '(("unread" . 'notmuch-tag-unread-face)
				 ("inbox" . 'notmuch-tag-inbox-face)))
(require 'notmuch)
