Merge "Themes: add ability to theme quick settings battery tiles" into cm-11.0
HeadsUp: Respect system decorations when adding view.

    - FLAG_LAYOUT_IN_SCREEN ignores system decorations, so
    a heads up view in landscape would end up underneath the navbar

    - FLAG_LAYOUT_NO_LIMITS allows the window to exceed the screen
    limits all together

      Removing both these flags makes Heads Up respect both system
    decorations and the screen limits.
