Release 2.0

This is the initial release of homebridge-delayed-occupancy but it is based on https://github.com/archanglmr/homebridge-occupancy-delay:1.0.1 so I'm versioning it at 2.0 as the config required by this new version is not backwards compatible.

The new syntax for config.json is:

"accessories": [
        {
          "accessory": "delayed-occupancy-sensor",
          "name": "Delayed Occupancy Sensor",
          "delay": 5,
          "switches": [
            "First activation switch",
            "Second activation switch"
          ]
        }
    ]

The switches list is optional. The plugin will always create at least one activation switch.
