swauth bins should default to the right port if no port is given

[Chuck Thier]

If you don't specify the port for the auth url with the auth bins, it dies with a traceback.

If a port isn't specified, it should be port 80 for http, and 443 for https

Traceback:

~/swift# swauth-add-user -A http://AUTH_SERVER/auth/ -K swauthkey -a acct user key

Might be better to modify http_connect() and http_connect_raw(). I'm not sure.
