The dummy button

[Issue]        http://suprem.sec.samsung.net/jira/browse/TWF-2222
[Problem]      The dummy button is needed by webview for focus
               managment.
[Solution]     Add #ifdefed the dummy button feature.
[Verify]       Open any webpage, dlogutil browser. Check if the
               dummy button is properly focused/unfocused and if
               webview focus is ok.
