Title: Add new alwaysOnTop window property to the Window State sample

The chrome.app.window alwaysOnTop property will be pushed to stable in M32. Add a demo of this property to the existing Window State sample app. The UI controls for this new option will be hidden in older Chrome versions which do not support the property.
