Potential plans for the EmailSigSprint

Here are some things we could do during an email sprint. I'm not sure whether there is 4 days worth of work here, or just two.

• Design the API for email v3.0
• Implementation of email 3.0 changes
• Fix references to codecs (i.e. CJKCodecs issue)
• Design and implement a new parser
• Implement support for more RFCs
• Write a suite of email address validators that doesn't depend on rfc822.py and is more consistent with RFC 2822.
• Other topics?
