/find support
/find allows a player to find both NPCs and items by a search criteria.  The syntax of the command is /find [-[npc|item]] <search criteria>

If the NPC/Item switch is omitted then both NPC and items are searched.  The method is fully asynchronous, and the items per line and the maximum amount of lines can be configured easily in the method; it's probably not worth adding dediated parameters this in the config file.
