    Option "None" replaced "Open" in Wi-Fi AP Settings of Wi-Fi Hotspot

    First option in Wi-Fi AP settings of Wi-Fi Hotspot, "Open", is
    changed to "None" since "Open" is not localized.
    "None" (@string/wifi_security_none) already in use in other
    Wi-Fi related screens and it is already localized in
    the existing source code.

    Settings: Fix password shown issue in landscape mode

    Fix the bug that the password shown as "........" with "Show password" selected
    after rotating phone to landscape mode in Set up Wi-Fi hotspot main view.

    Password textview and CheckBox will reset to the default after rotating phone to landscape,
    Add one static variable to save CheckBox's selected value.

    Makes the add button for new APNs appear in the action bar.

    The APN add button (a plus sign) now appears in the action bar if possible. The APN list interface is now more consistent with the WiFi list interface. Previously the user had to press the 'Menu' hardware button or the three dot button on the screen in order to reveal the actions.
