Add no-chill as a search filter/recipe type

[richard_mcateer]

Simple suggestion, few differences in great/method require major adaptations to a recipe. It doesn't really matter if a recipe is full volume, BIAB, batch sparged, etc., as long as you use the same temps and adjust grain to your efficiency. Hop additions, though, are quite different between no-chill and other methods due to the extended contact time. Would be handy to be able to quickly see recipes that used a no chill method.
