Tabs: dynamic titles#361

Now it’s possible to make dynamic labels or placeholders for fields, for example {​{​ page.title }}, but impossible to do the same for tab titles.

Would be very useful, as it could give extra clarity for clients, when they see tab like “Settings”, or “Seo” on some page - to understand, that these tabs are not general website settings, but of that certain page. Clients often call website - page, so when they see or hear “page”, they often think of website.
