Make develop cost a first class field in ICard

[Torgen]

instead of putting it in the effect.

@Torgen Could you please provide a bit more context on why this is necessary/useful? I don't yet understand what we would gain from this change.

On the card, the develop cost is at the top next to the regular cost, so it makes sense for it to be in a similar place in the app. If I'm reading the supply cards to someone out of the app, I would tell them the develop cost at the same time as the regular cost, not after the rest of the effect.

That makes sense - thanks for the explanation
