Parameterize ThroughputScorer
This makes the salient parameters of ThroughputScorer configurable
via an overlay.
Set the default parameters so that unmetered networks are preferred
over metered networks, and within each of those categories, saved networks
are preferred over suggestions. However, being the last-suggested network
can override both of these for a limited time.
