creation and destruction of JSDOMGlobalObject and event listeners.
        
Patch by Geoffrey Garen <ggaren@apple.com> on 2009-09-15
Reviewed by Sam Weinig.

Added an abstract operator==() to EventListener, to replace the
jsEventListeners set's role in determining if two event listeners are
equal from the DOM's perspective.
        
Added a type field to EventListener, and casting operations, to support
operator==() and other abstract operations.
