This patch is split off from D2863. It introduces a mace champion swordsman, using the black cloak actor, trainable at fortress and (with technology) barracks. This gives mace a much needed counter vs rams (athen has marines and spart skiritai).
The Thracian black cloak is historically justifiable as a Macedonian champion: Philip V of Macedon (r. 221–179 BC) had an elite unit of Thracians equipped with rhomphaia, black cloaks, and white shields, serving as a vanguard (Plutarch Aemilius Paulus 18.3).
