[done] AI should space out the buildings such that units don't get stuck

[sojourner]

At the moment the AI appears to place buildings at a constant spacing of '1' unit distance. That is smaller than some of the larger sized units. The most common of the units that get 'stuck' are the horsemen of tech faction and the turtle formation of the Roman faction.

Ideal spacing in my opinion is one which will allow any unit of one's faction and allies' factions to pass between any two buildings. However, just increasing the spacing from 1 to 2 seems to help matters a great deal.

Here is the code change I made:

Edit: Possible to set for every faction separately by ai-behavior control
