Tooltip on demanded technology

[Xyquas]

When AI demands technology, I want to be able to see what this tech does. I generally allow distribution of civil techs but not of warfare techs.

My request:
Add a tooltip for the line of the demanded tech which displays the same info as in the tech overview screen.

This would be a good idea.

This would be a nice thing to have.
