VisualLangLab 7: New Features and Tutorials

The latest version of VisualLangLab (http://vll.java.net/) has several
new features:

A new tutorial is available that exercises VisualLangLab with all the
examples and techniques in chapter-3, "A Quick Tour for the
Impatient", of the book "The Definitive ANTLR Reference" (see
http://vll.java.net/examples/a-quick-tour.html).

A new "WildCard" pseudo-token that matches any other defined token is
useful for recovering from syntax errors in the input.

Several other smaller changes make this latest version simpler to use.
