Growth on Barracks Removed

This was originally added before the Men-at-Arms where all lowered a tier each, so I've decided the growth isn't necessary any more and I want to encourage the use of the growth building.

Reverted the "Staying within the Peasant Economy gives +10% settlement building income" change as I felt it was inconsequential in the early game and not a buff the faction needed in the late game.

Added an Extra Foot Squire unit to minor settlements (level 2 and 3)
