Failed Starting Resource Placement

[smiley]

In extreme terrain or crowded maps where there are no/few viable positions to place resources, the base placement function fails to place the starting resources for the players, which results in an error message.

Currently, the placement functions have a fixed radius, and tries a random position on the circumference N times, where N is 30 for all resources except the mines, which is placed together for metal and stone, and therefore have 70 to account for more failures.

Rather than restricting the placement options to a circle, it would be better to increase the area of viable positions to be the annulus between the minimum distance and the maximum distance rather than the circumference maximum distance away.
