0.3.0

• Automatically check your configuration.yaml file any time it is updated using folder_watcher. You now can choose to use either the automatic checking setup or the Lovelace setup.
• Sensor now changes to checking while the check is in progress. This provides better clarity around when a check is in progress, and is also more friendly to automations so that you can tell when a check has completed and send a notification, for example.
• Documentation cleaned up and updated with new features and examples.
