Parse html links in the Notes section.

In the spirit of "Do the simplest thing that could
possibly work": capture Ctrl+leftclick mouse events
in the Notes area. If the string under the clicked
position is a valid url, then launch it.

Many common URI schemes will work. Typing a url that
starts with https:// will work. So will mailto: and
file://
