Added spring animations for tucking/untucking Floating Action Button

This change builds off of modifications from ag/24314702 to better suit animated tucking/untucking.
MenuViewLayer applies a clipBounds covering most of the screen excluding system/navigation bars
once the FAB begins a tucking animation. It does not remove the clip bounds until an untuck animation concludes.
