Fixes #1057 This PR adds `amenity=grave_yard` to the `landuse` layer. A unification function was implemented which encodes all `class=grave_yard` as `class=cemetery` in the tiles, which adds these features for existing users of `class=cemetery` with no change. The unification function can serve as a basis for any other tags that we might want to unify in the `landuse` layer. Tile rendering for an `amenity=grave_yard`.
