An item icon names an item, so the player can ask what it is wherever it
is drawn: a chip, a value stated as an amount plus a bare inline icon, or
an icon in a recipe summary. All three now show the item production
tooltip, with the amount beside the icon as part of the target.
An icon says nothing only where its display already carries a tooltip of
its own, since a display can only show one -- the build buttons, and the
module selection buttons, which are described controls whether or not a
given module fills its description in. On a clickable host the tooltip is
hover-only: the click belongs to the control.
The header bar's block stock loses its configured description in favour
of the production tooltip every other block icon shows, so
world.building_blocks_tooltip goes with REQ-UI-BLOCKS-TOOLTIP. It was the
only place stating what blocks are spent on, which no producer list says.
