Make farms more visable

[CarnageAce]

When you place several farms at once you can position them relatively well, but when you want to add a new farm next to an existing one unless its crops are growing its very hard to see the fence posts/poles sticking up.
The suggestion is to show the tilled ground perhaps with nice graphic furrows or simply just make the square of ground a darker colour or as a last resort have the farm highlighted when you press Alt key or something.
