The Device Selection modal consists of: - DeviceSelection, an overly smart component responsible for triggering stream creation and cleanup. - DeviceSelector for selector elements. - VideoInputPreview for displaying a video preview. - AudioInputPreview for displaying a volume meter. - AudioOutputPreview for a test sound output link. Store changes include is primarily storing the list of available devices in redux. Other app state has been left alone for future refactoring.
