v2.3.0 Testers Needed - HTTP Support for Motion Detect, HTTP/MQTT Support for Doorbell
There is now HTTP motion and doorbell support, valid commands:
 * Trigger Motion: `http://hostname:port/motion?Camera%20Name`
 * Reset Motion: `http://hostname:port/motion/reset?Camera%20Name`
 * Trigger Doorbell: `http://hostname:port/doorbell?Camera%20Name`

To enable HTTP support, set the port you want the server to run on in the `porthttp` config option.

For MQTT, the doorbell has been moved to a new topic, because of this, the default MQTT topic in the config has changed from `homebridge/motion` to just `homebridge`. To compensate for this, and because the previous version didn't properly read that config option, if you have `homebridge/motion` configured, `homebridge` will be used instead.

 * Trigger Motion: topic `homebridge/motion` with message `Camera Name` (same as previous versions)
 * Reset Motion: topic `homebridge/motion/reset` with message `Camera Name` (same as previous versions)
 * Trigger Doorbell: topic `homebridge/doorbell` with message `Camera Name`

I'll be updating the wiki with clearer directions later.
