Change the login flow for kiosk mode.

Change the login flow for kiosk mode.
Instead of showing the demo user UI, show the screensaver directly. On going active, the user gets dropped into a demo user session directly (see bug for details). Additionally removed the Lock Screen and Shutdown options from the wrench menu model for ChromeOS.
