Combine To: and Cc: headers

RFC 2822 only permits a single To: header and a single Cc: header, so
we need to turn multiple values of each of these into a list. This
will be particularly significant with a command-line option to add Cc:
headers, where the user can't make sure to configure valid header sets
in any easy way.
