Sample Fabric 'fabfile' for deploying to multiple hosts. Using: `fab deploy stage` or `fab deploy live`. Deploy to live prompts the user to confirm (with 'y' or 'n') that they actually want to deploy. Deploy tasks runs git pull & any number of utility commands (eg. asset compilation, checking / fixing folder permissions etc).
