Run a mail server in Python for debugging and receiving mail

[revalo]

FaqBot could host its own mail server using something like salmon. This will allow two things:

• Create a debug email address (for instance faqbot-debug@domain.com) all on its own for new users and developers to test things out without any mail setup on their part. This will make FaqBot truly plug and play.

• Eventually route all faq mails through faqbot's server and have it relayed to existing mailboxes. Esentially using this new mail server for prod and not just debugging.
