Proposal: flipped fmap in base (again)

Let's add <&> to Data.Functor then, as there is a reasonably clear
consensus and it already sees fairly wide-spread use.

I think we should leave ffor to another day and a separate explicit request
/ discussion, unless someone else on the CLC really wants to pipe up
strongly in favor of adding it today.

Adding the CLC to the distribution list to hammer out that detail.
