Pylint To Github

I spent a few hours trying to get the Jenkins Git & Github plugins to:

run pylint on all remote branch heads that:

arent' too old

haven't already had pylint run on them

send the repo status back to GitHub

I'm sure it's possible, but the Jenkins Git plugin doesn't like a single build to operate on multiple revisions. The repo statuses weren't posting, the wrong branches were getting built, and it was easier to write a quick script.

Now whenever someone pushes code at DramaFever pylint does its thing, and their most recent commit gets a green checkmark or a red cross. If/when they open a PR the status is already ready on the PR and warns folks not to merge it if pylint is going to fail the build. They can keep heaping on commits until the PR goes green.

I run it from Jenkins triggerd by a GitHub push hook, but it's setup so that even running it from cron on the minute is safe for those without a CI server yet.
