The power widget now uses the fuzzy-edged widget background.
It has a resonable layout in portrait and landscape.
appwidget_inner is the background for a button on the inside, with a border on the left.
appwidget_outer is the background for a button on the outside (i.e. leftmost); it
does not have a border.
Show packages included, time that a subsystem was on for.
Load label and icon in the background and cache the values.
Switch between totals and since-unplugged.
Other UI improvements.
This widget allows uses to turn on/off bluetooth, wifi, gps, and sync,
and adjust brightness without going through the settings menu.
The widget provider updates the settings when the buttons are pressed.
The widget provider is also a receiver for events indicating that the
status was updated elsewhere and the buttons need to be changed.
Shows sorted list of power usage (with some debug information) by the top 10
apps and subsystems. Doesn't yet take into account certain subsystems such
as data network usage, audio/video DSP usage, Bluetooth and lights other than
screen backlight.
Screen, Idle, Wifi and Voice usage and CPU time are accounted for.
Also need to add detail screens for each item and suggested actions.
