[Freeciv-Dev] (PR#2728) Game ends after Tech is researched

["ue80@xxxxxxxxxxxxxxxxxxxxx via RT" <rt@xxxxxxxxxxxxxx>]

Hi,

i've written a small patch that the game ends after a given tech is
researched. 

I wanted to do it:
set endtech "The Republic" but i didn't know how to get the space in.

So the commando is:
endtech The Republic

If its written wrong game will end at endyear otherwise it will end the
turn after the tech is researched with "Endyear YYYY"

Perhaps its useful for someone.
I used it to find the cases where AI needs to much time to get Rep.

Thomas
