Improved FAB UX.

One of the biggest issues with the FAB is that it doesn't
scale in/out properly. It looked more like setVisibility was
being called instead. This CL migrates the FAB controller to
use the built in scale in/out methods #show and #hide and the
animation is much nicer.

Some of the other issues were:
 - Now scaling animation is correct and visible.
 - No longer flashes when going in/out of search.
 - No longer shows on top of the return to call controller.
 - No longer bugs when switching between VVM TOS and contacts.
 - No longer shows FAB over VVM TOS when entering/exiting search
