Make the robusted donuts cost 2 utility credits

[TDHooligan]

robust donuts overshadow everything besides riot gas at the minute, but I wouldn't say they're too strong as an item. I think they're thematic, limited in usage and make security's already tedious job a require fewer visits to medbay regularly. None of the drugs they contain, besides Synaptizine, are even uncommon.

I do, however, think that security are given too many. I'd support them being halved in number and being made standard kit. The only issue is that security really don't have much useful equipment anymore to take up purchases.
