This patch is a follow-up to D3331/rP24566 and a prerequisite to D3320.
- The assembly gets more reasonable costs, garrison capacity, territory influence radius, and foundation resistance values.
- The Gauls can build their new assembly.
- The Gauls train their heroes at the assembly, instead of at the fortress.
- Because the assembly is functionally similar to the Athenian prytaneion, it can share its class and build restriction; the separate Assembly class is deprecated. (For comparison, the Persian Apadana shares a class with the similar Mauryan palace.)
