Pigs development

"Those pigs are getting more and more clever."- Maxwell on golden belt.

I think it'd be really cool if pigs could develop as the game (single world) progresses.

For example in the 1st 2 years pigs would act like now plus they'd be able to harvest berry bushes, grass and twigs. They'd aklso be able to pick up items like flint and rocks. After those 2 years the pigs would soon start to craft axes and chop nearby trees (faster than punching). Homeless pigs would be able to craft torches/campfires to not panic. Another 2 years pass and pigs actively plant trees as well as plant some seeds into the ground like Wormwood does. Another 2 years by and pigs now use spears and wear wooden helmets. They've upgraded their houses so that they take more hammer bashes to break. Pigs also consider picking up their vegetables, chopping trees and destroying houses as something bad and will attack the player.

The player would be able to speed up Pigs' development by building things like fire pit or lightining rod near pig king
