dojo and summerpalace for all civ

[tytannial]

It's interesting. There is a worker always dancing at the firepit for asian civs. The asian civs can always get 1 worker benefit buff from firepit, if they can build a firepit. Dojo and summerpalace are considered as a firepit. If you use the factory to produce banner army, it will fail. But the firepit can, because they truly train a unit.
