all: check markup modification time before converting to HTML

Previously, when the Convert, Watch or Serve running it will convert
all markup files into HTML without checking if the adoc has been modified
or newer than HTML file.

This changes check the modification time of markup file first before
converting them, to minimize unnecessary operation.
