Templating of prefabs

[ElmarJ]

Introduce "templating" of prefabs, which would allow us to set arbitrary fields on prefabs per geojson-feature from arbitrary feature properties (or even geometries - converted to unity-vectors and polygons).

This would allow for a much more decoupled, flexible and generic code-base, and also for merging the prefab-builder with the polygon-builders.

E.g.:

• property:name -> GameObject Name
• property:start-year -> ExistenceController Start
• geometry:polygon -> BlocksFromPolygon floorPolygon (converted to Unity polygon)

etc.
