Remove Nanoleaf API key and make it configurable instead of hardcode

[chpapa]

A quick change at Hackathon of X'mas 2017, we added Nanoleaf support to the code (at branch nanoleaf), however it hardcode the API key which is the URL to the Nanoleaf, and the theme to open in code. It should be configurable. (And not give up the API key of our office's nanoleaf! To avoid people come to our office / VPN and show red all the time lol)

Tasks:

• Make Nano Leaf URL (IP, port, API key) and effects name configurable
• Make daemon-opendoor fire trigger of door unlock / door lock, instead of hard code nanoleaf code in the middle of the code.
