Maybe deployment should be integerated into Hugo

[nathany]

I've mentioned my approach on this issue: https://github.com/spf13/hugo/issues/1543#issuecomment-211708203

This repo just contains files to include with "hugo new", whereas s3up could be a hugo deploy command that runs from CI or a local machine.

The challenge is that everyone has different preferences for preprocessors, CI providers, and deployment locations.
