Reduced the Korean Hwacha population cost to 0.

Fixed some scripting related to the heroes & legends mode.

Changed how the depopulator works, to relieve me of the need to manually add units.

Removed the Settler's bonus moves, and made the ancient civilian units (settler, builder, trader) and the missionary unit half-price (production and price progression halved).

Janissaries retain default behavior.
