deCONZ support

Added description to http status error (e.g. “403 Forbidden” instead of
just “403”).

Added a number of hacks for deCONZ support (see issue #112):
- Use the username from `users[‘undefined’]` in `config.json` for
unauthenticated GET `/api/config`.
- Use `config.mac` when `config.bridgeid` is not available.
- UPnP discovery of deCONZ.
