monkeysphere 0.30 invoking /bin/sh instead of /bin/bash

[Adam Soltys]

While running the command `sudo monkeysphere-authentication update-users` I received an error:
/usr/share/monkeysphere/common: 447: Syntax error: "(" unexpected (expecting "}")

This was a result of the script being executed by /bin/sh which was symlinked to /bin/dash rather than /bin/bash
