base

New shadowy status bar, direct from Z'ha'dum.

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.)
