Get rid of the hard coded lists like TERRAIN_IDS_LAND and reference TerrainLists from the XML instead

WIP towards initial city placement - markWithinExistingCityRadius working + unit tests

Add AI players + choose AI civs during game startup

First try at proper map cell data model including city data and worked tiles

Can correctly total up resources pulled in by farming the tiles around a city using CTP2's full/partial utilization formula

Calculate city size and worker utilization area

Fix package of TerrainCalculationsImpl
