Shen 12 is up

[Mark Tarver]

Shen 12 is now available by source and executables under Lisp. Two
main improvements are that macros are loadable under tc + with type
unit. Shen-YACC has incorporated a form which is equivalent to cut-
and-fail (Prolog negation) which improves the expressive power. I
have to update the learning page on this.

The learning page has a brief update - under compiler-compiler.
