- 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). git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@862 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
