Fixed long delay (virtual hang) when shutting down (deleting event sbbs_t)...

Fixed long delay (virtual hang) when shutting down (deleting event sbbs_t) caused by unnecessary call to hangup().
Events destructor now displays "BBS Events" rather than the last event node number (cosmetic only).
sbbs->output_thread only shows stats if bytes were sent (cosmetic only).
