patch changes - xml number changes

Its a little hard to go off topic when the topic is "all xml changes", lol.

The hill balance effect should go in a bonus building rather than breaking up the otherwise perfect progression of pacing across all yield buildings.

This isn't even a departure from vanilla, its just polish that vanilla should have always had and likely will one day.

A similar example is there's an Observatory for mountains and Solar Plant for deserts, but no research station or such for snow. This doesn't mean vanilla is lacking polish, it just means the extra building would probably be clutter on the tech tree since snow cities are less common on most maps.

The flatland building already satisfies both the need for a building-production modifier and a flatland bonus. Splitting it into two buildings might be slightly advantageous to gameplay, but not much, and has the downside of increasing scope creep.
