Downloads: No financial bonusses for ai

As this table's column names are still unknown, I had no frame of reference to adjust these values.
What I opted to do instead is copy the values for a human on each difficulty to it's AI counterpart:
E.G human_on_easy_difficulty copied to AI_on_easy_difficulty,
and so on for each difficulty.
This means you will still earn less/more depending on the difficulty you choose, but now the AI will have the same increase or decrease.
