Fixes for i18n digest to work.

Mailman/Queue/Switchboard.py:
    listname is returned in unicode.
    ( '\x80' + 'a' is OK, '\x80' + u'a' is NG)
Mailman/Utils.py:
    Utils.oneline() is extended for returning unicode string.
Mailman/Digester.py:
    next_post_number is not used anywhere.
Mailman/database/listdata.py:
    Attributes added (esp. for non web u/i)
Mailman/bin/senddigests.py:
    Initialization
Mailman/Handlers/ToDigest.py:
    Internal string calculation is done in unicode.  So, several fixes.
    StringIO is used because cStringIO doesn't have encoding attribute.
