Potential missing package issue
Hiya, I upgraded to latest, and homebridge failed to boot; my system was missing `hap-nodejs` which appears to have silently become required in the latest package. Stack trace:

```

```

Resolved with `sudo npm i -g hap-nodejs` but I think there might be a package.json issue somewhere at play here.
