- Add off-screen rendering support on Windows. This involves a number of new CefBrowser and CefHandler methods. See the "Off-Screen Rendering Example" in cefclient for example usage.

- Add CefRunMessageLoop() for efficient message loop usage and modify cefclient to use it.
- Add CefHandler::HandleNavStateChange() for back/forward state notifications and modify cefclient to use it.
