Ann: SWI-Prolog 7.1.5

Hi,

I have uploaded SWI-Prolog 7.1.5.  Highlights:

   - Quite a few changes in PlDoc to support the NEW WEBSITE!  With
     big thanks to Anne Ogborn, Jessica Chan and Wouter Beek.  There is
     still work to do, such as re-organizing the download page.  But,
     the site looks better (I hope you agree) and is much better structured
     for new users.  Comments welcome.

   - Various changes to enhance the support for and fix bugs in handling
     dicts.  Some work on strings.

   - Support dicts in the JSON libraries.

   - Lots of small stuff.

	Enjoy --- Jan
