Development from Hunter-Gatherers to Farmers

[angusthompson]

The first transformation being introduced is the development of farming from hunter-gatherer communities. Here is how it will work:

• When the tile you control reaches a population of 20, the decision to start a farming community becomes available.
• When this button is pressed, a farm is built and 80% of the hunter-gatherers in your controlled tile are converted into farmers.
• In farms, hunter-gatherer populations start to decrease as farmer populations rise.
• As they reach the pop cap, the farmers colonise neighbouring fields, causing knock-on attrition on the hunter-gatherers there.
• Other tiles which reach populations of 20 will also start to develop farms.

TODO

• Make a robust tile selection function
• Make a button to become farmers
• for now...

Only the AI development of farming remains to be done.

• Add a condition where a tile with 20 pop has 30% chance to form a farm, population become farmers.
• Slow the spread of farming.

The chance of random pops forming a farm has been reduced to 15%
