Framework: Quick Access Ribbon (Part 1 of 2)

This patchset removes power widgets and replaces it with
a smaller version of the quick settings panel.

ps7- squashed this commit and this: http://review.pac-rom.com/#/c/1997/
together. renamed mRibbonQS & added an extra onChange method in PhoneStatusBar.
added missing attributes in QuickSettingsContainerView (this killed
duplicate tiles in landscape at this moment, will fix later).
