MHng: A modern (N)MH clone

This is designed to be a complete rewrite of NMH that's designed to
work in a modern mail enviornment.  That means IMAP, SMTP, GPG, etc.
Connect to a SSL-enabled GMail server

This doesn't actually do anything with the new connection, but it does
at least connect to Google's IMAP server and then proceed to let me ^C
it... :).
