Add: Campsite Editor to Map tab.
Allows users to set whether there is or is not a villager visiting the campsite, allows selecting that visitor and to edit the visit timestamp (defaults to current timestamp override so visitor is there on same day load).
Back-tracked offsets from old Cylindircal Earth save schemas for old save revs.
If campsite is not unlocked on the save, the UI is locked out with a message.
Cleanup: Moved UpdateFruitsFlag to misc editor class over save class because that was bad form. Oops.
Added fruits + flowers to Player Misc menu (kept field goods property manager in place still).
Saving fruits pushes change to flags block for fruits so that multiple edits aren't required when changing/saving it with new UpdateFruitFlags method.
Flowers added as enum class like Airport Color, but should be moved out to strings for localization later on.
