Integrate wutali

    Integrated with Wutali's changes in a way that allows them to be safely pulled in to hnakamur/vagrant-fabric-provisioner, to take advantage of edits made to https://github.com/wutali/vagrant-fabric. 
    
    Conflicts:
        .gitignore - Whitespace
        Gemfile - Added documentation
        LICENSE.txt - Name change (resolved in favor of hnakamur)
        README.md - Added additional usage and contribution instructions.
