Fix Cookie.py: Fix example in the docstring (encoded SerialCookies contain

unicode now). Fix _quote() and Morsel.set() which were using str8.translate().
As cPickle.dumps() returns bytes now value_encode() and value_decode() methods
must encode/decode (however output() might better return a bytes object).

 Be warned, however, if SerialCookie cannot de-serialize a value (because
 it isn't a valid pickle'd object), IT WILL RAISE AN EXCEPTION.
