kawa 3.0 released

[Per Bothner]

Kawa 3.0 is now officially available.

The biggest new feature is that most places where variables can be defined
can now take a pattern and/or a guard.  Conditional forms such as 'if', 'and',
and 'match' can also include patterns.  Partly to support this, the implementation
of how Kawa calls unknown procedures was changed.

There are also a lot of changes in the implementation and API for strings.

For a longer list of changes with more details, see:
