[RFC] [PATCH] emacs: Add support for saved search accelerators.

Subject: [RFC] [PATCH] emacs: Add support for saved search accelerators.

Extended the saved search definition to allow the inclusion of an
accelerator key for the search. Bind 'j' in the common mode map as a
leader for such accelerator keys.
---

This arose out a conversation in #notmuch and Mark's patch to extend
the saved search custom specification based on requirements for an
external package (Austin's notmuch-go.el).

Re-organising the layout of the saved searches is missing (as it's
lots of fiddling about with absolute numbers and I didn't want to
waste time on it if this is going nowhere), so the saved searches may
not all line up correctly in notmuch-hello.
