Ann: SWI-Prolog 7.1.9

Hi,

I have uploaded SWI-Prolog 7.1.9.  Highlights:

   - Various issues with functional notation on dicts: expansion in
     clause heads, defining user functions, support in the development
     environment (colouring, source location in the tracer).
   - Processing dicts in stack traces.
   - Fixed source location tracking for some DCGs and inlined calls for
     phrase/2,3, forall/2, once/1 and ignore/1.
   - Several updates to pengines.
   - Semweb: fixed turtle bug (DoS attack: could eat all memory on malformed
     Turtle.  Added RDFa parser.
   - Installer: fixed installation issue with precompiling libraries for the
     Windows installer.

	Enjoy --- Jan
