Home Assistant integration with light example

[newtonheath]

Some hackery to allow a Presto to integrate with Home Assistant.

config.py
configuration with host, token, and entity configuration

hampws.py
class to provide access to Home Assistant

hampws_light.py
demonstration of a button that reads state of a light from Home assistant - shows the state on screen as a button either yellow for on or black for off - will continue to read state and update if the light state changes outside of the Presto - will also allow the user to touch the button to turn the light off and on - huzzah!

hampws_test.py
some test code for some of the methods in the class - could do with some improvement for sure - there are some heavy logging outputs here, but for sure will help the user to learn some of the back and forth

Thank you.

Could I trouble you to move these into examples/home_assistant please? The HA specific config feels weird in the root.
