Enqueue preview scripts.

These scripts normally are enqueued just-in-time when a playlist shortcode is used.
However, in the customizer, a playlist shortcode may be used in a text widget and dynamically added via selective refresh, so it is important to unconditionally enqueue them.

	require_once dirname( __DIR__ ) . '/media.php';

	wp_playlist_scripts( 'audio' );
	wp_playlist_scripts( 'video' );
