creating a new page.

It is mostly so we can show 'No title' for page name and to have a
'back' button instead of 'edit page' when viewing ones own page.

But we don't need it as a page has a title when we click 'add page' as
we make the new view entry in database straight away and the title
will be something like 'Untitled v.2'.

And if we change the title on page settings form then block edit screen
will now show new correct title instead of 'No title'
