Star-sky ZigBee ZLL conversion

Description
May 29, 2015
Upgraded the star-sky ceiling with a custom ZigBee controller (Silicon Labs Thunderboard Sense-based) which can be integrated into a Philips Hue network.
Had to reverse-engineer and debug some of the ZLL-related communications, and that resulted in a series of bug reports internal to Silicon Labs due to the protocol specification being too loosely defined.
