BREAKING CHANGES STARTING WITH 2.2.0-beta1

As with all beta versions, please remember to backup your configuration.
Automatic configuration backup is coming, at least I'm working on it :)

Breaking change:

Please read 2.2.0-beta1 release information for breaking change details https://github.com/hass-agent/HASS.Agent/releases/tag/2.2.0-beta1

Fixes in comparison to 2.2.0-beta1:

• Fixed HASS.Agent crash when no WebView screen was explicitly configured #346

Small and quick release but since this bug causes crash of HASS.Agent I wanted it fixed as soon as possible :)
