IDialog:
-Added several new functions for dialogs' new visual attributes, as well as a way to add, get, create, remove, and clear dialog images.
Global NPC events:
-Added fields and variables from the old ScriptEvent events, in preparation to replace the old events with NpcEvent instances on local NPC scripts.
-Fixed issue where some event hooks would run on remote worlds.
Global NPC killed event:
-Added droppedItems and expDropped fields.
IWorld and NpcAPI:
-Now always uses a non-remove WorldServer object to create ScriptWorld objects and add them to the world cache.
All NPCs activate these scripts. If a player wants to create a script that's universally used by all NPCs, this allows for that to happen with a lot of ease!
