The actual reason is that the 2.2.0 servers send the conn_ping packet before
checking the capability of the connecting client. Your patch would work, but
it's very complicate. Mine just move the send of the connection ping after
the capability check.

This is the responsibility of every hacker to keep their server compatible,
dealing with the capability string.

This is not related, but this should be fixed, I will commit it.
