[ale] SSH Port forwading/tunneling

[attriel at d20boards.net (attriel)]

If the SSH drops, then the tunnel goes.  If the SSH manages to stay
connected, then the tunnel (in my experience at least) should stay up.

If you have a stateful persistent connection through it, things might get
wonky b/c something gets dropped in the middle, but most protocols account
for brief outs i think

not sure on restarting it ; i use the ssh terminal for IRC anyway when i'm
on, so i have to reconnect if i get fully dropped.
