Added Monoid instances for Property and RevertableProperty.
* Added Monoid instances for Property and RevertableProperty. * Removed applyToList. Instead, use mconcat. (API change) Eg, if you had: applyToList accountFor [User "joey", User "root"] use instead: mconcat (map accountFor [User "joey", User "root"]) mappend x y is basically the same as x `before` y. In particular, if x fails to be ensured, it won't ensure y. This seems to make sense, since applyToList had that behavior, and so does the Monoid for Propellor Result. The alternative would be to try to ensure both and combine the results. However, I don't see any reason to do it that way. It would be nice if the description of both properties were displayed when ensuring the combination. But then, it would need to display eg: ensuring x..ok ensuring y..failed ensuring x and ensuring y..failed Without a way to get rid of that redundant last line, I don't want to do that. Note that the haddocks for the Monoid instances need a really wide screen to display! This is IMHO an infelicity in haddock, and I can't do anything about it really.
