Erik Montnémery	https://github.com/emontnemery	Changes to entity naming

There have been a couple of changes to entity naming:

• Marking an entity as the single main feature of a device is now done by explicitly setting the entity's name property to None, implicitly marking an entity as the single main feature of a device by not setting the name property is no longer supported.
• Unnamed entities from certain platforms now get a default name based on their device class, this includes binary_sensor, button, number and sensor entities.

More details can be found in the entity naming documentation.
