Define order for more vocabulary home page properties

[osma]

Fixes #1100

This PR defines the order of some properties commonly used for concept scheme metadata:

• foaf:homepage
• dc:license
• dc:rights
• dc11:rights
• dc:relation
• dc11:relation
• dc:created
• dc:modified
• dc:date
• dc11:date

Thanks to @MikkoAleksanteri for helping to define the order.

Here's a crude screenshot (stitched from two parts...) of the HERO front page after the change:
