Remove dependency to CPP: removed stuff related to CPP calls

Now that the built-in parser has support for all the feature of CPP
being used by WindowMaker's default menu, we can remove the stuff
related to calling CPP:
 - code for preparing and running CPP;
 - compile-time option to de-activate the call to CPP;
 - command-line option
