Implemented: Clock, brightness, silent toggle, airplane mode
(although this seems not to be working well yet on the
device).
Unimplemented: Orientation lock, battery, wifi signal, date.

Artwork is FPO but serviceable enough. Many hardcoded font
colors & styles were moved to styles.xml where they belong.
AM/PM finally given the old heave-ho (but configurable in
StatusBarPolicy.java).
Notification content remains on a light-gray background for
now (so as not to screw up custom RemoteViews) but status
icons will definitely need across-the-board rework to look
better against a dark background.
(Re-integrated on top of new status bar code.)
