Use different FAB for dialpad, and use new animations.

+ Use scaleIn/scaleOut for FABs in the Dialer application.
+ Add assets for green fab.
+ Update dialpad fragment, both the Java and layouts, to have their
own FAB containers and FABs.
+ Change DialpadSlidingLinearLayout into
DialpadSlidingRelativeLayout.
- Removed or relocated dial some FAB handling, visibility, and
translation functions. Now that the FABs in the dialpad fragment
and DialtactsActivity are distinct, the logic can be scoped more
precisely to a particular fragment/view.
