LSELFENERGY: the frequency dependent self energy

 LSELFENERGY = .FALSE. or .TRUE.

default: LSELFENERGY=.FALSE.

If LSELFENERGY=.FALSE., QP shifts are evaluated. This is the default behavior.

If LSELFENERGY=.TRUE. the frequency dependent self-energy $\langle \phi_{n \mathbf{k}} \vert \Sigma(\omega) \vert\phi_{n \mathbf{k}} \rangle$ is evaluated. Evaluation of QP shifts is bypassed in this case.
