Maximum and Minimum monoids

[Gershom Bazerman]

I agree that it's more correct to leave them as semigroups. The real 
path should be to move the semigroup package into the platform for the 
next release. (And, eventually, subsequent to that, to remove First and 
Last from Data.Monoid entirely).

Cheers,
Gershom
