Make the robusted donuts cost 2 utility credits

[nefarious6th]

my only problem is that would leave anyone on the just a baton loadout with potentially one useless credit and only one utility if they wanted to do donuts and donuts; but I could also see keeping them at 1 credit and having the loadout of donuts just be one red and one blue as a compromise too. That way someone could still get the two extra donuts from the third utility token and eat up the token
