[Freeciv-Dev] patch: a bit better easy level

[Per Mathisen <permath@xxxxxxxxxxx>]

AI players now prefer Monarchy. They will use it exclusively after
Monarchy has been researched. My own testing suggests that the AI
will go for Republic before researching Monarchy, and since I did not want
to muck with the research code, I let it use Republic in the meantime.

I am not sure how effective this is, but it seemed to work pretty well for 
me.

Yours,
Per
