Log anything to error log with pretty printing

	 * @description Takes any message and sends it to the error_log. Due to how php's serialize works (will add binary characters) and that error_log will truncate when it hits a binary character a str_replace is used.
	 *
	 * @param $message mixed anything you want to print out
