Reroll Coins shop using ranked medals#339

it would be nice to be able to re-roll the coins shop other than by simply waiting. This also would give another use for ranked medals if you already have all of the stuff in the ranked shop or simply don’t want anything else from it. You could hyypothetically spend ~100 medals to re-roll the coins shop to see if you can get one of the things you want instead of just waiting it out.
