Mushrooms grow persistently as mushroom trees

[TealNerd]

Would be nice to have as it would improve mushroom farming overall and allow us to have everything persist

Suggested timings:

• Forest, Nether, Swamp: 72h (yes 3 days)
• Mushroom: 6h

And nerf regular mushroom spread to 1/10th of current chances.

why 6 hours for mushroom? I thought we where targeting no idle needed timings, which I guess 6 hours is close as it would only require four harvests per day.

What're the others at? 12hrs? Could bump it to 12hrs, either way we'd need to rebalance mushroom utilization in XP recipes.

Should all mushrooms grow into giant mushrooms if they have room?
Should small mushroom spread be completely disabled, or nerfed? We could have both: control spread like we do now, and convert a mushroom to a mushroom-sapling with bonemeal.
