Galaxy S Style Power Widget

Change-Id: I27970609f71a2e53e39d276102900d51b763f785

Make it so the widget shows as on by default.

Only modify the view of the bar, if we want to.

Check to make sure the Uri we are modding is the one we want to.
This is to prevent the bar from be disabled for some paradoxial reason.

Added Flashlight button for devices with an LED. And a Sleep button

Don't instantiate unused power buttons in StatusBarService.

New power buttons in the StatusBar is a great thing. But, on my HTC Hero,
I got a lot of the following error in logcat:

This is beacause, all power buttons are instantiate, even if unused or
functionnality is missing. So, I remove most calls to getInstance() for
all of them and use a HashMap to store the buttons used and only call
them in updateStates() and updateWidget().d

Additionnaly, my change reduce memory usage of the status bar.

Fixed tabs, some indents and long lines.
