Research center graphics should change based on what has been researched.

The title is pretty explanatory but for the sake of clarity:

- Game starts with a research center containing only one small building.

- Each technology added creates a new building or makes an existing one bigger: so the first electricity tech you research should create a new building and the advanced electricity techs add floors or features, like maybe the last tech for electricity adds a Tesla coil to the top of the building.
