Add pauls dotfiles

I have added a small install script to install Paul's dotfiles. This script has to be called from user vagrant. I first tested it with sudo su and then scripted it to test to make all steps work in the Vagrantfile itself. But there is a problem calling the ./install-deps.sh which does something strange on line 6:

    Resolving deltas: 100% (282/282), done.
    ./install-deps.sh: 6: ./install-deps.sh: Syntax error: redirection unexpected
    Already up-to-date.

Running the commands from user vagrant all works fine. So to integrate the PR we propably change the sudo's in the Vagrantfile inline script to run as user vagrant instead running with sudo'ed shell.
