Updated balance.x to include anti-chariot, anti-elephant bonuses for javelins.

balance.x amended with new entries for Alexander and The Hellenistic Era. However, not all units have been covered - early Roman units certainly have not had entries made for them as victims of Scythe Chariots.

All Armenian units now have proper voice lines.

Phase 1 of 2 to add Georgian and Armenian voices underway. Armenian infantry all speak, as do Georgians.
- Fixed an issue with one version of Machairophoroi not having any voice lines.
- Replaced old coding that stopped buildings from appearing.
