This patch:
- changes the weapon of gaul infantry swordmen to (Celtic) csword, because all other Celtic swordsmen (cavalry, champions, heroes, ptol mercenaries) use it already and the spatha is a Roman cavalry sword;
- changes the weapon of athen cavalry swordsmen to falcata (kopis/makhaira), a chopping sword, because ancient sources (e.g. Xenophon) emphasize cavalry used that, not a xiphos (similar to gladius or akinakes), a short stabbing sword, unsuitable for horsemen
