- Provide default implementations of the file chooser dialogs (open, open multiple, save) on all platforms (issue #761).

Browse Source 
- Add a new CefBrowserHost::RunFileDialog method that displays the specified file chooser dialog and returns the results asynchronously (issue #761).
- Add a new CefDialogHandler::OnFileDialog callback that allows the application to provide custom UI for file chooser dialogs (issue #761).
