Msgflo

* Fix `getSource` for participants started by the runtime

* Fix spec/heterogenous participant test enforcing wrong discovery message.
The messages sent to `fbp` topic must have a wrapper with protocol=discovery and command=participant.

* Update to msgflo-nodejs 0.5.x, which does not install transport libraries (`mqtt` or `amqplib`) automatically.
You must now install these as dependencies yourself.

* Initial support for [fbp-spec](https://github.com/flowbased/fbp-spec), a data-driven testing tool

* Added `msgflo-send-message` utility program, send message to MQTT/AMQP queues
* Added `msgflo-register-foreign` utility, allows to declare MsgFlo participant discovery data
for existing systems which don't have native MsgFlo support.
* Added `msgflo-jobstats-newrelic` tool, for downloading statistics from the New Relic integration
about how long it takes to execute jobs. Can for instance be used to tune an autoscaler like [guv](https://github.com/the-grid/guv)

Released: 15 June, 2016

* Added ability to define component libraries in `.json` file.
Each compononent has a command which can be used to instantiate such a component.
By default the key `msgflo.components` in `package.json` is used.
* Added `msgflo-procfile` for generating [Heroku Procfile](https://devcenter.heroku.com/articles/procfile) stansa, from component library + FBP graph.
* Added ability for `msgflo-setup` to also start up participants, from component library + FBP graph.
