Removing titan-cassandra's dep on org.jboss.netty
Removing titan-cassandra's dep on org.jboss.netty

This was added by aa5a5bfd7f3e35a30bbed3d67c3c96cd44fdfb04, "add jetty
[sic] dependency required by C* native protocol".  I don't think it's
actually required anymore, or at least, it seems to be have been
superseded by the netty 3.6.6.Final jar now in the dependency tree.  I
can start the embeddedcassandra backend and load GotG without this
jar.  I can do the same with an standalone Cassandra process started
through titan.sh.

The this particular netty jar causes problems with.  There remains at
least one path to this old jetty artifact via HBase 0.94.
