Ask for full information (jid, server address, ssl/tls, ..) when freetalk.scm is not configured

When the user connects for the first time (freetalk.scm still not configured), he will be prompted for only his jid, which is not sufficient when the xmpp server only authorizes ssl/tls connection. login.scm contains some code which already exists in connection.scm, so I deleted them. Is that too much ?
