Better support for "funny" characters in subject prefixes.

CookHeaders.py will now be aware that subject_prefix can be a unicode
string.

_setValue(): Capture changes to subject_prefix and canonstr() it,
meaning convert html references to unicode characters.

getValue(): Capture access of subject_prefix and uncanonstr() it,
meaning convert any non-list-charset characters to their html refs for
error free display.
