Fix of wrong "alive" status in scoreboard.
This commit fixes the issue: https://github.com/assaultcube/AC/issues/21
Player in spectate mode isn't dead, so when he switches from spectate to active mode, he is still non-dead.
Therefore d->state=="CS_DEAD" doesn't work in such cases.
This commit removes also some aimless line.
