Changed default entity grouping on the frontend.

Changed from `type` to `category`, which is basically the `name_plural`
attribute of the associated entity type metadata.

This allows us to define distinct entity metadata entries that we still
want to share the same grouping - for instance, `temperature_sensor`,
`humidity_sensor` and `battery` should all be grouped under `Sensors` on
the frontend.
