Changes in parse.P to allow XSB to serve as an external preprocessor for Prolog
programs.
Added --ignore command-line option to make it possible to ignore the remaning
command-line arguments. Needed to ignore the file name, which is tacked on to
all XSB preprocessors.
Added the 'NOWARN' wrapper to silence the spurious warnings produced by the
conditional compilation code.
Added explanations to the manual to show how to use XSB as a preprocessor.
Some fixes in the curl manual.
