Treatment of SOC in Wien2k

As a matter of fact, we need the output for the DFT band structure for both spin directions explicitly. That means that one needs to do a spin-polarised DFT calculation with SOC, but, however, with "magnetic moment set to zero". In the Wien2k initialisation procedure, one can choose for the option -nom when lstart is called. This means that the charge densities are initialised without magnetic splitting. The SOC calculation is then performed in a standard way as described in the Wien2k manual.

Note that the final "x lapw2 -almd -so -up" and "x lapw2 -almd -so -dn" have to be run on a single core, which implies that, before, "x lapw2 -up", "x lapw2 -dn", and "x lapwso -up" have to be run in single-core mode (at least once).
