Show price/etc from previous quarter

Not sure how this would be worked into the GUI, but right now it's really hard to find the sweet spot for price, etc, because you only get to see how the profit & capacity changed from the previous round. It would be fantastic if the prices or number of flights from the previous round could be shown as well, so we could quickly see that raising prices on a route hurt the overall profits, etc. I have to keep scribbling notes on paper to remember which routes I raised the fare on.
