Fixed inconsistency in rhovalnew (transverals spin components were not calculated correctly)

Added a Bfield routine that adds (non-collinear) magnetic fields in KKRhost.
The routines only work in the newsolver.

By default write out log file only on master rank (activate all ranks with `write_all_ranks` test option)
