        - Phase 2 in the JS API.

        - Added support for specifying static tables of values -- this should
        obviate the need for using complicated callbacks for most lookups.

        -  API objects are now created with classes (JSClassRef) -- in order to support
        static values, and in order to prevent API objects from storing their
        data inline, and thus falling into the oversized (read: slow and prone to
        giving Maciej the frowny face) heap.

        - Added two specialized JSObject subclasses -- JSCallbackFunction and JSCallbackConstructor --
        to allow JSFunctionMake and JSConstructorMake to continue to work with
        the new class model. Another solution to this problem would be to create
        a custom class object for each function and constructor you make. This
        solution is more code but also more efficient.

        - Substantially beefed up the minidom example to demonstrate and test a
        lot of these techniques. Its output is still pretty haphazard, though.

        - Gave the <kjs/ preface to some includes -- I'm told this matters to
        building on some versions of Linux.

        - Implemented JSValueIsInstanceOf and JSValueIsObjectOfClass

        - Removed GetDescription callback. Something in the class datastructure
        should take care of this.
