Animate floating action button

DialtactsActivity now implements ViewPager.OnPageChangeListener,
so that it can animate the floating action button in response
to page changed events in ListsFragments. Because ViewPagerTabs
also needs to listen to page changed events and ViewPager only
supports one OnPageChangeListener, ListsFragments is now in charge
of listening to page changed events from ViewPager and firing off
the same events to multiple OnpageChangedListeners
