Check minplayers/teams only upon respawn.

Closes gh-496. New can't-re-enter-spawn protection was conflicting with
the minplayers/minteams check that used to bring back everyone to spawn
as soon as the limit was hit. From now on, you will only be stopped from
exiting the spawn after your next death. This is how it probably should
have been implemented from the start - much less brutal when a player
leaves the match suddenly. :)
