Add some basic framework for controlling the LIFX bulbs.

Queries for LIFX gateway and bulbs.
Manages connection pool for LIFX connections from the server.
Skeleton for majority of packet processing and basic bulb tracking set
up.

Chose not to commit the visuald projects generated by dub for now, since
they depend on the other dependencies that dub pulls in (vibe, openssl,
etc). May re-evaluate in the future.
