Gitconsensus

Going forward when GitConsensus sees a `version` in the `gitconsensus.yaml` file that is higher than what it expects it will treat that repository as an unconfigured one. This will ensure that an install of GitConsensus which has not been upgraded will not misinterpret a future version of the consensus rules that it does not understand.

This version also adds some more explicit checks to various functions with the goal of making sure changes only occur to repositories that are configured for it.

Pull requests were not timing out as the `shouldClose` function was still using the old rule version.

Both of these upstream dependencies have newer major versions that this gitconsensus version upgrades to.

This release is primarily focused on cleaning up and normalizing the GitConsensus rules. It also provides a new `init` function for initializing new projects.

In addition this is the first release from the new home (the gitconsensus org on Github).

This release takes much of the core code and turns it into a reusable library.
