(getplayer): There may be multiple players for the same country in the
list of players, but at most one in state PS_PLAYING.  getplayer()
used to get the one first in the list.  However, its callers need the
one in state PS_PLAYING.  In particular, typed_wu() notifies the
player obtained from getplayer().  If the player in state PS_PLAYING
isn't first, say because another one is trying to log in, the
notification gets lost.  Fix by making getplayer() return the player
in state PS_PLAYING.
