Reviewed by Maciej.

• 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.
