Include KE forces in Pulay forces

[davidbowler]

At the moment, when Iprint is high enough, the force breakdown includes Hellmann-Feynman local and non-local (though technically phi-Pulay NL forces are included), Pulay force, KE force, ion-ion force and then PCC and non-SCF forces if applicable. But the KE force is just part of the phi-Pulay forces, and should be added in here. (Trivial but important.)
