[PATCH v4 5/5] notmuch-emacs-mua: do not create a frame by default with --client

[Jani Nikula <jani@nikula.org>]

Make the default behaviour for --client the same as emacsclient
default: do not create a new frame. Add a new option --create-frame,
passing the same option to emacsclient to create a frame.

---

v2: fix killing frame with --create-frame

v3: fix --create-frame w/o --client parameter check

v4: fix kill terminal logic, document behaviour with daemon mode
