[Freeciv-Dev] (PR#13142) fix sciencebox/researchcost compatibility bugs

["Jason Dorje Short" <jdorje@xxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13142 >

This patch fixes two bugs with compatibility of researchcost/sciencebox
values.

1.  Current CVS games cannot be loaded in 2.0 because of a typo of
"game.researchcost.".

2.  2.0 games loaded in current CVS need to have the researchcost
multiplied by 5 (to make it a percentage).
