We now fade between security screens when not coming from selection view.
In the case of SIM PIN/PUK screens, this means we show the user's security
screen without going back to the selector view.
This change also adds a fade animation for when we go between security screens
without going back to the selector view.
This also fixes a bug where we were invoking two checks for the SIM
state - one for ACTION_DOWN and another for ACTION_UP.
