Iterate on data usage chart UI.

Switched to inflating chart views from XML, using attributes for
configuration.  Start using drawable assets for chart components
instead of manually painting.  Include hand-cut assets, and animate
between states when touched to invoke.

Clamp sweeps to valid chart ranges and prepare for sweep labels.
