Other predicates and features defined by default

Author(s): Daniel Cabeza.

To simplify the use of Ciao Prolog to the first-timers, some other predicates and features are defined by default in normal cases, to provide more or less what other prologs define by default. Here are explicitly listed the predicates defined, coming from several libraries. Apart from those, the features defined in Definite clause grammars and Enabling operators at run-time are also activated.
