Advanced farms control

1) A toggle button for farms' UI that prevents seeding food crop if fertility is below certain threshold. So if the toggle is on, then fertilizer-dependent cycles (corn-potato, f.e.) wait for fertilizer supply to ensure fertility never drops, otherwise farm just pauses waiting for the fertilizer supply.
For that I propose the following game logic: when crop changes, if the new crop is of a kind that lowers fertility (corn, potato), then the farm will go pause before seeding it unless fertility is equal or above the threshold (100% minus last crop drop, so if last crop was potato, then threshold is 90%, if corn - 85% and so on).
As a result, when fertilizer is adequately supplied, farm will run non-stop, but if not, then farm will pause waiting for it, instead of depleting the soil.
2) A toggle button that prevents seeding food crops if the farm' storage buffer will not be able to hold expected amount of food.
