Heavily refactor the deploy.rb file to work locally.

There have been a few changes here:
 - Directories are properly created and changed in ownership;
 - Capistrano deploys to the local VM using the private keys that are
 setup automatically by Veewee built boxes;
 - Bundler is executed automatically on the finish of deploying code;
 - Foreman exports an upstart configuration for Ubuntu.
Add a few ignores into gitignore.
Add an actual 1.9.3 version as shorthand may not work.
Update the README with more links.
