Name the opponent, and stop making phones squint

The transition turns your opponent into a zombie with variant 'c', and the
roster table had no row for it — so the stats screen fell back to the raw key
and the shambler sprite, and the list appeared to hold two shamblers. He is
THE OPPONENT now, and he is not the racket zombie, who keeps coming back.

Type across the menus was sized on a desktop and read tiny on a real phone:
tabs, opponent names, counts and labels all go up a step, and the roster
sprites go from 34x46 to 48x62.
