>Summary: rfc822.AddressList and "<>" address

Initial Comment:
rfc822.AddressList incorrectly handles empty address.
"<>" is converted to None and should be "".
AddressList.__str__() fails on None.
I got an email with such an address and my program
failed processing it.

Example:
>>> import rfc822                                     
                                                        
>>> rfc822.AddressList("<>").addresslist
[('', None)]
>>> str(rfc822.AddressList("<>"))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.1/rfc822.py", line 753, in __str__
    return ", ".join(map(dump_address_pair,
self.addresslist))
TypeError: sequence item 0: expected string, None found

Patch is attached.
