[Beta4] [Feedback] Extreme sensitivity to starting resources

I find that the game has extreme sensivity to start-location variables, in particular to gold mines.

I recommend that the map script be less sensitive to this; either every civ should start with a gold mine, or none should.

Otherwise, its the difference between +1 income or +6.  Thats not really very fair.

Start position usually matters for these kinds of games, but not quite to this extent.
