Fixing zmq transport to work with latest version of seneca transport
Additional dev dependencies
Merge branch 'chico-master' into seneca-0.5.20
Working with 0.5.20, some more improvements needed
Use seneca-transport utils
Change to use REQ/REP rather than PUSH/PULL + tests
 - Not using pipelining, opening 2 ports unnecessarily
 - Pipelining should be done via seneca rather than 0mq
