Zones are no longer able to delete expeditions. World now tracks empty
expeditions in cache and only deletes them when it detects an
expedition's dynamic zone instance has no more clients inside.
This fixes an exploit where lockouts couldn't be applied to expeditions
after all members were removed because zones were deleting the expedition
immediately. Clients still inside the dz were able to complete events
before being kicked from the instance while not having an expedition.
Expeditions are no longer purged from database in the world purge
instance timer to avoid a possible race with this new system
This implements a small cache in world to track expedition states.
This fixes expired expeditions being left in zone caches unless the
expedition's dz instance was running to detect it (or unless an
expedition was deleted via a client using /kickplayers). This was also
leaving clients in a ghost expedition that no longer actually existed
