Balance hellenic champions.

Double the metal cost of elite spartan citizen soldiers, as they have
stats near those of champions.
Use a more reasonable cost for age 2 champions.
Differentiate the armored swordsmen from the other sword champions by
actually increasing it's armor.

This was SVN commit r18249.
