Adds components `ChannelListing` and `ChannelListing` item with visual test. Essentially a more simplified version of the existing `ChannelSelectionOverlay` component. Correctly implements `IFilterable` behaviour to filter child channel items. Channel joined state is based on the underlying `Joined` bindable of the `Channel` class. Channel join/leave events are exposed via `OnRequestJoin` and `OnRequestLeave` events which should be handled by parent component. Requires a cached `OverlayColourScheme` instance to be provided by the parent overlay component when added.
