When tapping on the password field in the win8 logon dialog, make sure it gets focus, and also make sure that the onscreen keyboard appears. Specifically: implement doAction 0 for this object to do setFocus (this UIA object has no invoke pattern) and also in globalCommands's review_activate script call accNotifyTouchInteraction if this was a touch gesture, so that this is communicated to Windows.
