Only one "keydown" event will be attached to the window, and the onKeyCodeListen() function will delegate which listeners should be called according to the event.keyCode fired.  - Fixing bug in the persistent mode (related to the new console panel) - Improving the accuracy of the delay time calculated in the persist process.
