update CommitInfo to new github api

use job.name instead of job.toString in GH comments
try to get job started comment right away
one more job -> job.name
desperate attempt to get things going and see what's happening
only comment when build is still running
make buildStatusForJob a stream
use job.name for rebuild detection

added some logging
be more optimistic about build having started
in absence of a better way -- should add a uuid param to be sure
sad kitty shady json fix
when started job doesn't appear and job queue is empty, retry
discard irrelevant (default) jenkins params when looking for job for PR&branch
Merge pull request #12 from adriaanm/github-api-changes

some love for the kitty
