default plant parts when harvesting crops

[Skud]

When I go to harvest a crop, after I select which crop it is (eg. tomato), it should automatically select "fruit" (or whatever is the most common plant part to harvest) for me.

If I come from the crop page by clicking on the "Harvest this" button (eg. if ?crop_id=NN is set in the URL params) then this should happen when I first land on the page. Otherwise it should happen when I select something from the dropdown.
