extension of the ready-restart feature:

extension of the ready-restart feature:
- bugfix: extend the pause for rotting health when map is being reset, otherwise health will start to rot after the 10 second countdown is over, because the rot is set to 10 seconds
- new feature: sv_ready_restart_after_countdown: allows player to walk around during countdown (and prevents that a player knows where he spawns as he gets spawned after the countdown is over)
- new feature: sv_ready_restart_repeatable: players can restart the map more often (more than once)
- new feature: sv_ready_restart_nag: nags other real players who haven't readied up yet to do so, interval and duration can also be setup
