Create run.sh

README.md would obviously need to change one line to:

` wget -q https://raw.githubusercontent.com/scrapinghub/portia/master/install.sh -0 install.sh && (chmod 755 install.sh; ./install.sh)`

So would last install.sh line which has `wget` for `run.sh` - not sure on a better way to do this.
alternative (and simpler IMO) boostrapping:

    wget -qO- URL |bash

or

    curl -Lfs URL |bash
