#65 Closing EQ2World exe too early can cause client async save to not complete

We need a delay added to make async saves complete first, right now it just auto destroys. Need some safer logic here.

For the time being all players should be logged out at the time of shutdown or risk character corruption. Can get stuck on loading entities (char select->enter world) typically if corrupted.

This should not be a problem with a ctrl+c signal 11 shutdown, we can now properly close out. If someone were to kill the process though no promises!

11:59:37 D World : The world is ending! 11:59:37 D World : Shutting down zones... 11:59:37 I World : Shutting down all zones, please wait... 11:59:37 I World : Zone shutdown complete 11:59:37 D World : Shutting down LUA interface... ^C11:59:45 I World : Exiting... we hope you enjoyed your flight.
