DashboardView: Not recreating btns on frame change

Formerly, whenever the frame was changed we would recreate every button;
this would cause them to be animated from the upper left corner of the
parent view. By simply calling layoutButtons, we can smoothly animate
the buttons to their new calculated position on orientation / frame
change.
