Create webhook for presence change

[redakker]

Some people don't use the MQTT server.
For these users implement a webhook solution.

So the user can configure a URL which is called if the BLE beacon is appeared or is gone.

Use wildcards for device name: {device} and presence {presence}

For example:
http://mywebhooks.com/presence/{device}/{presence}
or
http://mywebhooks.com/presence/{device}?presence={presence}

Webhook should be configured for each observed device.
With this solution, devices can be controlled directly without any home automation hub.
