Chocolatey Packaging

Add scripts to build chocolatey install packages. One package installs to the global modules location in c:\Windows the other installs to the installing user's Documents module location.

If this is accepted, I assumed that @lzybkr would want to upload and own the package on Chocolatey.org. If not, I can upload the packages if I notice a new release in Github.

I would also suggest that Githubs release functionality be used to store release binaries rather than checking in the built packages directly in the repo.
