Hiding unused fields

There are many NPCs that do not give out part-time jobs or repair items. For those NPCs, I suggest hiding those two fields if they are not set. I would also suggest doing the same for Location if the NPC does not have a specific location. And Occupation should also be hidden in the few cases where it is not used, such as for Triona.

If you can code it, go for it~

That's not a problem since I've already implemented it in a sandbox.

That is some messy coding... There are a lot simpler ways to have done it.
