Like a MAC address, a valid username can only contain 6 pairs of
hexadecimal characters, and for homebridge purposes must be
colon-separated. This adds a simple regex test for a proper username,
since I just spent nearly 24h trying to debug an issue that all came
down to not realizing that a MAC address could only have letters A-F
(see https://github.com/nfarina/homebridge/issues/385).
- Homebridge calls single exported initializer function and passes an
API object
- No more require() for HAP classes (doesn't play well with plugin
structure)
- Homebridge is now designed to be `npm install`d globally and
executed via "homebridge" script
- Remove all specific accessories/platforms except for an example
- New internal structure and "cli"
