OpenAtlas

For OpenAtlas Discovery we decided to make a new format out of Linked Places so we can experiment and test it without breaking the original format.

• Added relations.relationTypeLabel to have the property label without property code and the right locale (?locale=[en, de, ca, es, fr]) if available.
• Changed relations.relationType to the correct reference with _, eg. crm:P2_has_type
• Adapt types: typeHierarchy. Ordered list of objects with label, id and description.
