Add BrowserCommandController Interactive Test

BrowserCommandController interactive test ensures the recent changes of browser shortcuts in fullscreen won't be broken by unexpected changes. It starts a full screen browser window, sends several key events normally consumed by browser, and checks whether these events are caught by the web page.
