Bump homebridge version to 0.4.29.
- No longer requires a
"name"key in config.json; - FirmwareRevision now reports Sonos version;
- Homebridge throws an error, prompting you to update, when NodeJS or homebridge versions used don't meet the requirements from package.json. homebridge-zp now specifies the minimum versions as requirements in package.json and issues a warning when higher version are used.
