6292
	 * This methods removes all of the registered css files on the front end
6293
	 * from Jetpack in favor of using a single file. In effect "imploding"
6294
	 * all the files into one file.
6295
	 *
6296
	 * Pros:
6297
	 * - Uses only ONE css asset connection instead of 15
6298
	 * - Saves a minimum of 56k
6299
	 * - Reduces server load
6300
	 * - Reduces time to first painted byte
6301
	 *
6302
	 * Cons:
6303
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6304
	 *		should not cause any issues with themes.
6305
	 * - Plugins/themes dequeuing styles no longer do anything. See
6306
	 *		jetpack_implode_frontend_css filter for a workaround
6307
	 *
6308
	 * For some situations developers may wish to disable css imploding and
6309
	 * instead operate in legacy mode where each file loads seperately and
6310
	 * can be edited individually or dequeued. This can be accomplished with
6311
	 * the following line:

6313
