Several little fixes

- Fix take_gold function adding to party gold instead of subtracting
- Fix wandering NPCs not appearing if the town was stored in a save slot
- If IF_FIELDS node called while outdoors, skip to jumpto
- If IF_STATISTIC called on selected target with whole party selected, default to cumulative check
