[PATCH v2] notmuch/emacs: Observe the charset of text/html parts, where known.

David Edmondson dme at dme.org

Add the charset of text/html parts to the JSON output of 'notmuch
-show' when it is known. Observe the encoding when rendering such
parts in emacs.
---

Add the charset only for text/html parts to avoid incorrectly
declaring the charset for JSON inline text/plain parts (as they have
already been converted to UTF-8).
