[tor-talk] Tor Talk footer needs have an extra blank line before it

[Yuri]

tor-talk messages trigger BODY_URI_ONLY (+1.0) in SpamAssassin when 
somebody writes a message with only one paragraph, without the trailing 
blank line. The footer that ML attaches has no blank lines and URI in 
it, and SpamAssassin thinks the message and the footer are all one 
paragraph, and the message is likely a spam for whatever reason.

ML needs to either add the blank line before the footer, or lose the footer.
