Automatic WiFi Config

The below will setup automatic WiFi configuration via text file. The way this will work is you plug in a USB disk with a file named wifi.txt with the essid as the first line and password as the second line in the file. On boot a small script will run that reads the file and re-configures the PiFrame's WiFi to use the new values.

Can be used for setup and/or re-configuring WiFi if something changes.
