Message.getaddrlist(): This now handles multiple occurances of the

named header, so that if a message has, e.g. multiple CC: lines, all
will get returned by the call to getaddrlist().  It also correctly
handles addresses which show up in continuation lines.

AdderlistClass.__init__(): Added \n to self.CR which fixes a bug that
sometimes, an address would contain a bogus trailing newline.

Message.getaddress(): In final else clause, added a test for the
character we're at being in self.specials.  Without this, such
characters never get consumed and we infloop.  Case in point (as
posted to c.l.py):

To: <[smtp:dd47@mail.xxx.edu]_at_hmhq@hdq-mdm1-imgout.companay.com>
----------------------------^
otherwise we'd infloop here
