mu4e: rework html2text conversion

Browse Source 
Rework the conversion from html to text; the functions doing that now
expect to receive one parameter, the message, and return the converted
message.

In the old way, the function got invoked in a buffer with html text, and
were expected to modify it to text. This old way is still supported for
backward compatibility.

If @code{mu4e-html2text-command} refers to an elisp function, it is
expected to take the current buffer in html as input, and transform it
into text (just like the @code{html2text} function).
If @code{mu4e-html2text-command} refers to an elisp function, the
function is expected to take a message plist as its input, and returns
the transformed data.
You can easily create your own function, for instance:
@lisp
(defun my-mu4e-html2text (msg)
"My html2text function; shows short message inline, show
longer functions in browser."
(let ((html (or (mu4e-message-field msg :body-html) "")))
(if (> (length html) 1000)
(progn
(mu4e-action-view-in-browser msg)
"[Viewing message in external browser]")
(mu4e-shr2text msg))))
(setq mu4e-html2text-command 'my-mu4e-html2text)
@end lisp
