Please address my comments from the first patchset. These methods should be
moved to WebLocalFrame.

 
     // worldID must be > 0 (as 0 represents the main world).
     // worldID must be < EmbedderWorldIdLimit, high number used internally.
     virtual void executeScriptInIsolatedWorld(
         int worldID, const WebScriptSource* sourcesIn, unsigned numSources,
         int extensionGroup, WebVector<v8::Local<v8::Value> >* results) = 0;

     // Call the function with the given receiver and arguments, bypassing
     // canExecute().
