Minor changes in DFPT+U
- DFPT+U with ortho-atomic orbitals is disabled, because it is more complicated than it was expected. First, Hubbard forces in pw.x must be extended to ortho-atomic orbitals and then DFPT+U must be reconsidered.
- Update the reference files for example18 for DFPT+U
- Various minor changes
