[web2py] PGP Mail

[Massimo Di Pierro]

Thanks to szimszon we have PGP in Mail (trunk only)

mail.send(
       self,
       to,
       subject='None',
       message='None',
       attachments=None,
       cc=None,
       bcc=None,
       reply_to=None,
       encoding='utf-8',
       cipher_type=None,
       sign=True,
       sign_passphrase=None,
       encrypt=True,
       )
Please check it. Should
       cipher_type=None,
       sign=True,
       sign_passphrase=None,
       encrypt=True,
be set at the send level or at the mail.settings level? Do people tend  
to use different passphrases for different emails or the same one?
