WIP: Learning OSM by figuring out how to map the Victorian Pride Centre.

Building (Way #45378417):
Levels: B, G, M, 1, 2, 3, 4 (rooftop) → building:levels=5, building:levels:underground=1, roof:levels=1
Contains multiple organisations (Nodes?), use addr:floor.

Organisation (Node #12387775701) is one Node within the Way. Maybe this Node should represent the the building managed by this Node?

Reconcile "Community Centre" and "Community centre" tags.
