New 7punches App Switching Guide

A new guide has been added for 7punches App Switching. This guide is designed for POS operators that want to use 7shifts for labor and don't want to integrate using the API. This allows the installation of 7punches into a POS and you are able to invoke the app via a URL and it will switch back to the POS application once the time punching is complete. Android support only at this time.
