Add disciplines.vams and enough syntax to parse it. This is part of the standard disciplines header file, with enough syntax to part the natures and disciplines included. Don't do anything with the parse results yet.

Support for the begin_keywords directive. The begin_keywords directive allows the source code to select keyword subsets so that a bit of code that uses identifiers that class with a newer version of the standard can still be compiled.

Check ketwords against active keyword subset mask. The begin_keywords directives manage a mask of keyword sets that are active at a given moment. This patch makes the lexor actually test the given keyword against the mask. If it matches, return the keyword id, if it is disabled then it is an IDENTIFIER.
