Correction of TWIDDLE_CLASSPATH when runnig against JBoss server

Hi,

I was trying to run your twiddle tool with the JBoss EAP 6.2 server and I've hit a problem that jboss-client.jar was not on path and getting exception that jmx-remote protocol unknown. I'm sending this pull request and suggesting a fix on it.

Cheers
