Adjust style of button
Currently, a `homebridge-http-switch` is always displayed as a button:

**Feature Request:** It would be great if I could add a property to the json config that it would be styled as a door lock button, e.g. `"style": "door-lock"`.

This would enhance the look and feel of the button.
