Issue #188:

- Add a CefV8Context object and CefV8Value::ExecuteFunctionWithContext method to support asynchronous V8 ExecuteFunction callbacks.
- Add a CefFrame::GetBrowser() method.
- Ensure that V8 types are only referenced on the UI thread.
- Accept a empty |object| parameter to CefV8Value::ExecuteFunction.
