Add menu option to lock screen when viewing card

When passing a phone to a clerk to scan the barcode, if the
phone is rotated and the screen reloads it can be bothersome
or confusion. To avoid this situation, a new option is
added to lock the screen.

A menu icon is now added which defaults as unlocked. When
touched the app sets its orientation to the "natural" orientation
of the device. When touched again the sensor dictates the
orientation of the device.
