Change default value of kap_dc from 1.0 to 10.0 as well as the recommendations.
This is based on the magnetic monopole tests. It indicates that kap_dc = 10.0
reaches the best balance between damping and advecting. kap_dc = 1.0 advects
well but damps much slower. kap_dc = 100.0 seems to turn the problem into a
stiff one and it fails to either damp or advect the divergencies away when
compared to the other two cases. The recommendation then goes to use values
between 1.0 and 10.0.
