Fix to stop pre-buffed character trains

There is a problem with trains of pre-buffed characters, people fully buff up their characters to be ready to rush out if they get logged or to help a friend who is being attacked.

This fix is made to try and stop that so a player cannot just rush out with a armada of pre-buffed characters till their enemy is down.

If a player logs in a safe zone like an Inn or Adventurer's Hall and the setting is set to TRUE the player will lose half their mana and have all their buffs purged off. However if they log off in an unsafe zone aka they get a logoff ghost, nothing will happen. It would be stupid to purge the buffs of someone being logged, they would be doomed, so this is just for those logging off in safe zones.
