Teach where research data comes from, and say so when it runs out

Browse source 
The scanner quest moves ahead of the gas burner and gains the hunt it exists
for: a research lab world, which pays several times what an ordinary planet
does and is the only reliable source of research data. Finding one is what
the scanner is FOR, so the conquest record now remembers which kind of world
was taken and a quest can ask for that kind.

Bombers get a pair of quests after the transporters. That pulled the ship lab
up with them - a vessel is unlocked AT the lab, so asking for a bomber before
one exists would have been unfinishable, the same trap second_hull fell into.

And both research screens now explain a shortfall instead of hiding it. The
skill tree refused a doctrine in silence; the ship lab said "already queued
or complete", which is not why it refused and sends the player to look at the
wrong thing. Both open an explainer naming what was wanted, what is held, and
where data actually comes from.

#192's rule - a tool is taught immediately before the quest that needs it -
now points at the scanner's FIRST use rather than its only one, with the
world survey still required to follow it.
