[Freeciv-Dev] (PR#8632) Easy way to set map size with auto ratios (seteables if desired)

There is some agreement that we should have a 'side' parameter but no
'ratio' parameter.

However if there's no ratio parameter, I don't want all the extra code
for the ratio parameter.  No map.ratio is needed and no 10xratio +
yratio hackiness.

If we later decide we do want the ratio to be user-controlled, it
shouldn't be too hard to add it back in.
