Use binary protocol

Hi Dan,

I've updated [ciql](/nulu/ciql) to use the [cql-rb](/iconara/cql-rb) gem that uses the native, binary protocol to talk to Cassandra in place of the Thrift-based [cassandra-cql](/kreynolds/cassandra-cql) gem.

This PR updates the adapter to use it. (And updates the devtools, too.)
