The flags for the network firewall, screen brightness adjustment, and
data saver are essentially to decide whether to turn on these features
or not, so having them be *_disabled is confusing for someone to read.
These flags differ from others such as animation_disabled or
vibration_disabled, which are actually turning off features instead of
enabling them. I'm updating the internal variable names and adding
documentation to make the behavior clearer. I haven't changed the flag
names themselves since that could make things a little more difficult if
someone wants to set flags later on.
