circle-target-branch-check

Simple service to attach a Github status message to Pull Requests, with the current CircleCI status of the PR's target branch.

When a CircleCI build completes, this looks for any open Pull Requests based off the branch that was built, and posts a status to each one informing the PR author whether their target branch is red or green.

When a Pull Request is opened or pushed to, this asks CircleCI for the latest build for the PR's base branch, and posts a status to the PR.
