Converted scenarios from Civ2

I was playing around with a Civ2-to-Freeciv scenario converter I've been working on and produced the following ports from Civ2.

Note: These scenarios are for Freeciv 3.2.1+

There's quite a number of failing sanity checks after loading these, when sanity checking enabled in the freeciv server. You may want to build your freeciv with -Ddebug=true to check those.
Likely related ticket I opened some time ago: https://redmine.freeciv.org/issues/2018 (but that addresses only a small fraction of the failed sanity checks)
