Limit advanced WebSocket handlers to servers that support them

Older servers (back to v1.1.3 I think) do support WebSocket rules, but
only for passthrough/close/timeout. Still useful, but not so much. We're
not worrying about older versions here - the stats suggest that's far
less than 0.1% of users, and nothing will break for those users, it's
just that their WebSocket rules won't be set (by the rules store check)
so any rules there will be ignored.
