	 * Pros:
	 * - Uses only ONE css asset connection instead of 15
	 * - Saves a minimum of 56k
	 * - Reduces server load
	 * - Reduces time to first painted byte
	 *
	 * Cons:

	 * - Plugins/themes dequeuing styles no longer do anything. See

	 *
	 * For some situations developers may wish to disable css imploding and

	 * can be edited individually or dequeued. This can be accomplished with
