Website Name and Description slugs should NOT be editable

[fibonacid]

Issue

If go inside the dashboard structure edit page you can edit the slugs of the field settings "website-name" and "website-description", but if you do that the sites breaks without explanation.

Proposal

It would be better if those fields were presented as locked inputs, as they do in the component edit page.
