Achievements were only checked when the achievements screen was opened, so a
new one was never celebrated. After every game the HUD now refreshes the player
from the server (the purse counts up, a level-up fires if earned), runs the
achievement check and drops a gold banner for each new one with its coin
reward, the reward jingle and a haptic.
