More API action.
        
        - Headerdoc finished

        Semantic Changes:
        - Added a JSContextRef argument to many functions, because you need a 
        JSContextRef for doing virtually anything. I expect to add this argument
        to even more functions in a future patch.
        
        - Removed the globalObjectPrototype argument to JSContextCreate because
        you can't create an object until you have a context, so it's impossible
        to pass a prototype object to JSContextCreate. That's OK because (1) there's
        no reason to give the global object a prototype and (2) if you really want
        to, you can just use a separate call to JSObjectSetPrototype.
        
        - Removed the JSClassRef argument to JSClassCreate because it was unnecessary,
        and you need to be able to make the global object's class before you've
        created a JSContext.
        
        - Added an optional exception parameter to JSFunctionMakeWithBody because anything
        less would be uncivilized.
        
        - Made the return value parameter to JSObjectGetProperty optional to match
        all other return value parameters in the API.
        
        - Made JSObjectSetPrivate/JSObjectGetPrivate work on JSCallbackFunctions
        and JSCallbackConstructors. You could use an abstract base class or strategic
        placement of m_privateData in the class structure to implement this, but 
        the former seemed like overkill, and the latter seemed too dangerous.
        
        - Fixed a bug where JSPropertyEnumeratorGetNext would skip the first property.

        Cosmetic Changes:
        - Reversed the logic of the JSChar #ifdef to avoid confusing headerdoc
        
        - Removed function names from @function declarations because headeroc
        can parse them automatically, and I wanted to rule out manual mismatch.

        - Changed Error::create to take a const UString& instead of a UString*
        because it was looking at me funny.
        
        - Renamed JSStringBufferCreateWithCFString to JSStringBufferCreateCF
        because the latter is more concise and it matches JSStringBufferCreateUTF8.
