a block's spacing sits with its title; page settings need the page selected

Spacing had a link in the chrome painted onto the page and lost its door with the
rest of it. It belongs beside the heading: both are properties of the selected
block, and one of the two is not worth a place of its own to go to.

The page's name and address now show only when the page row itself is selected.
With a band or a block open they sat above an editor about something else and
read as belonging to it.
