view: wrap To: and Cc: headers in HTML display

It is common to have large amounts of addresses Cc:-ed in large
mailing lists like LKML.  Make them more readable by wrapping
after addresses.  Unfortunately, line breaks inserted by the
MUA get lost when using the public Email::MIME API.

Subject and body lines remain unwrapped, as it's the author's
fault to have such long lines :P
