Relocated island/sister fruit/flower functionality to new FruitsFlowersEditor out of MiscPlayer to better follow existing layout.
Added new button for this editor to Map tab for the new form. MiscPlayer fruit now sets passport only, FruitsFlowersEditor sets both. Other functionality remains as before.
Retired FieldGoods from the Map button in favour of above.
Adjusted UI anchors and open positions for new forms + cleaned up recent lang_xx string additions.
Add theme menu to Editor and accompanying logic + strings.
Updated Misc fruit/flower and CampsiteEditor to use translatable strings.
Added new strings to lang and msg files.
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.
