Subject: Removed the create_npc wrapper and the last two NPC callbacks

When creating an NPC, you now provide its optional talk and update functions
directly rather than them being stored in a table on the Lua side and then
called in response to a global callback.

Also fixed an issue with a missing gender parameter to the delayed NPC
creation callback used by NPCs defined on the map (found by Erik while
reviewing this patch).
