Add crop quality

[joskuijpers]

Add quality of fills.

Quality of bales (added to bales)
Quality of grain, stored in Fillables and in Storage.
Many more places when needed.

When there is 1000L of quality 100%, and 1000L of quality 50% is added, it becomes 2000L 75% quality. As in, it is a simple running average.

Quality depends on moisture.
Quality deteriorates over time.

MP: add single event to update quality / or calculate locally / something. Maybe hook into existing events.

When selling we don't need to adjust volume, only price so lower quality is worth less
Another option for animal feed is to reduce productivity if you feed low quality feed
We could maybe also increase the spilled food amount when feeding low quality stuff
Also suggest that when trying to feed low quality (under let's say 60-70%) we deny it in the through and display an onscreen message saying the animals won't accept it as it's bad
When quality is even lower we turn it into manure

Possibly also add:

• density layer for tipanywhere. Can also be used for rotting
• food quality in husbandries determines meat/milk quality.
