[grain] type plant always produce the same weight of grains

[caethan]

I've been playing with the plant modding and found an odd inconsistency. 

For most plants, when I want them to produce seeds, I can modify the weight of seeds produced with the SEED_VOLUME and SEED_SIZE properties, as follows:

pinch, S: 0.007358 lbs (e.g., turnip seeds)
fistful, S: 0.022075 lbs
pinch, M: 0.036792 lbs
pinch, L: 0.044150 lbs
fistful, M: 0.110375 lbs
fistful, L: 0.132450 lbs

Any plants with the type [grain] in the header line, however, always produce a unit of grains weighing 0.110375 lbs, equivalent to a fistful of medium seeds, regardless of how I set the properties.  You can see this with both barley and rye, both of which produce small fistfuls of grains, each of which weigh 0.110375 lbs.

True indeed. Checked out the code and grain type plant's fistful size is hardcoded for some reason.
I can't remember why that sort of decision has been made, especially as flora files have seed_size defined for grains...although it's defined as Small, which is a bit off for the grains in the game. Gotta reason my reasoning regarding this at some point.
