Configure brightening screen when display a barcode

Browse Source 
When a barcode is displayed the screen's brightness is set to
the maximum, in an attempt to provide the best chance for a barcode
scanner to capture the barcode. However, it may not always
be desired to increase the brightness, for example when using
the app in low light.

This change adds a setting to control the screen brightening
behavior when a barcode is viewed.
