Randomize NPC locations

[anmart]

Would be fun to randomize npc locations - take the newly uncovered npc map data and just shuffle the NPC IDs around

Some things to consider

• off limits areas. Might have to prevent certain areas from being randomized
• Ronald. Very hard coded to appear in entrances
• end of duel tables would need to be adjusted
• movement and scripts with multiple npcs would break

I guess this is a bigger task than I thought.
in the mean time, there could be a lost of early changed NPCs and could ignore the others. Would still have to figure out end of duel tables, though.
