Rundeck runner

Need to add 3 env vars to heroku:
* RUNDECK_PTOPIA_JID
* HUBOT_RUNDECK_TOKEN
* HUBOT_RUNDECK_URL

To test you can use:
`RUNDECK_PTOPIA_JID=5b6b227f-17e5-4c36-b27f-6c737bef057c` 
That JID is the "Test echo" job which is set up like the "deploy - ptopia" job 

It will take in a branch name from the deploy manifest and echo `I am a <branch_name>`

I'm trying to come up with a good way to parse the the list and determine which job_id to use, but failing to come up with a good solution. Thing is I don't want to have to `process.env` on each emit.  Got any ideas?
