Fixes for wifi side of GCD prototype

1.  Moved actual device indicator to config.json
2.  Wireless interface now part of config.json
3.  LED path now part of config.json
4.  udhcpd config now generated by script

This should make the script a fair bit more robust and allow it to work on any
machine.

In addition, updated the SSID to the new format.
