Frameworks: add ability to change the color in battery saver mode (1/2)

User complain about the ugly orange....give the user the ability to change the
color in status and navigation bar if battery saver mode is activated.

Especially for you Tylog :D

PS
- move it into the observer...method is called to often to call every time
  the settings value for it.

Return: Listanimation Views and Interpolator [1/2]

PatchSet:
    - optimize more:
    - call provider values only when needed and do not fire them permanently.
      so just do it if scroll state changed.
    - as well go out of the setAnimation method as soon as possible. We
      handle here methods which get called 10000 times during scrolling
      so we need to be as fast as possible.

PS:
- initialize the animation modes default to off just to be sure

PS:
- move state change out of OnScrollListener
- reduce the provider value call to only one call

AICPfy lp5.0:
Bring it to Lollipop
Settings menues don't animate and fuck me if I know how to fix it
