Sort boosts by price doesn't work well for late-game boosts

[michael-s-crouch]

Would it be reasonable to have goats and/or flux crystals added to the front of Molpy.priceComparisons? (currently Molpy.priceComparisons = ['GlassBlocks', 'Sand', 'Castles']; ). This has been particularly annoying for me because I've had "3D Lens" as my "cheapest" boost available since before I had infinite castles, but that particular problem won't be as bad with #1474 fixed. But still, it seems like the natural price order.
