Proposal: newtype for applicatives of monoids

IIRC the accessor is still called getApp in reducers, which is slightly
inconsistent. Perhaps it'd be worth fixing on some future release that will
bring other incompatible changes.

Thanks

To offer a couple more colors for the bikeshed:

In my old monoids package, this exists as App:

In the newer reducers package, it has been shortened to Ap:
