Valid shebang lines for the setup.sh scripts.

[dflock]

If you run the current setup.sh scripts like this:

chmod +x ./setup.sh
./setup.sh

you get this error:

bash: ./setup.sh: /bin/bash;: bad interpreter: No such file or directory

To fix this, you can either remove the trailing semi-colon from the current shebang line:

#!/bin/bash;

or use a better, non-hardcoded shebang:

#!/usr/bin/env bash

which should work on a much wider range of shells.
