Commit efcfd7e7cdf281b4f3c43dfe6ede4b6eab09f10c

Added MD_SPAN_A_DETAIL.is_autolink (#181) This allows the processor to tell whether an <A> tag is the result of an autolink, and customize its output. For example, I want to emit an autolink of an image URL as an <IMG> tag, and an autolink of a YouTube URL as a video embed.
