This gives a lot more flexibility to the user to cover bandwidth, power,
and privacy issues related to network traffic. The current implementation
does not represent these prefs as well as it should. For example, it does
not force the traffic over the preferred network type if the other type is
set to "never". Instead it just tracks the "unmetered" status of the
active network, and acts based on that.

Left some more unused strings which are a bit more general purpose and
perhaps should wait until after a stable release to remove. The
rationale for this is that we may want to revert to part of the old
terminology in certain places, and don't want to have to ask everyone to
translate everything again.
This makes it a lot easier to setup all the testing stuff. Mostly,
I'm tired of fighting Android Studio's fragility, so I want to remove
as much non-standardness as possible in the hopes of improving that
situation.
