Demoshop: The second SEO category label

[jakubhavlak]

As an e-shop operator, I want to be able to set up a label category so I can support my SEO.

Acceptance Criteria:

• For each domain, the administrator can separately set the second label for the category listing pages for each domain
• The administrator can identify them easily - ideally the label above and below the listing
• The customer sees the set label above the listing of the products in the category
