Monitor updates to pr and post Jenkins CI progress

Background and further details here: nodejs/build#236

I'd be happy to chip in here.

@phillipj Looking at @jbergstroem's work for the build team in that linked issue above, I see he/they are using the Github Status API. That seems like a cool way to go... maybe incorporate that in to the work you have in pollTravis?

[Fishrock123]

Yeah we should probably push to the github status API. That way, it also displays at the merge button and you don't need to find the latest comment.

[Fishrock123]

Related github module API: http://mikedeboer.github.io/node-github/#statuses, looking into it.

[phillipj]

@williamkapke trying to use to status API sounds awesome! One step closer to mimic Travis completely 👯

moving the status api discussion to #14

@jbergstroem how would we know when to start polling? Could Jenkins do a HTTP requestagainst the bot, notifying there's a PR build that just started? Or should the bot listen for PR comments matching "CI: http://ci.nodejs.org/*"?

[jbergstroem]

I owe a few of you a post -- sorry for the delay. I'm a bit backlogged at the moment; will get back to you shortly.

Seems the ../api/json endpoint would be perfect for polling build status. E.g. for nodejs/node#6342: https://ci.nodejs.org/job/node-test-pull-request/2363/api/json

Landed with #35
