Move Hash::Merge -> Hash::Merge::Augment, new Hash::Merge from Hash::Merge::F

Original Hash::Merge is incredibly slow due to the MONKEY. This is
someone that is very unlikely to be what people want. App::Assixt
reports parse time to go from 13s to 7s on first run, 13s to 0.3s on
subsequent runs, which is *massive*.
