Remove public farm plots or instance them

Currently there is a problem where there are not enough public farm plots to go around, which leads to bad feelings among the playerbase when other players occupy or over-occupy these plots. This problem will only continue to get worse as the playerbase grows.

I propose that we either remove public farm plots and expand the number of private farm plots (maybe this is something that can be upgraded with gold/pioneer credits and/or via apartment) or instance the current public farm plots so that every person can use them themselves.

This would also open up additional game design options for crops since you would no longer have to design around needing to cycle crops in shared plots (e.g., you could potentially remove crop death and instead replace it with some kind of quality mechanic wherein the sooner you harvest a crop, the higher quality it is)
