clusters/halo: Determine magnetic field by fraction of its energy density
* Rewrite "magnetic_field()" function to calculate the mean magnetic field
strength within ICM according its energy density fraction w.r.t. the ICM
thermal energy density.
* Remove config options "b_mean" and "b_index", which are replaced with the
option "eta_b", the assumed magnetic energy density fraction w.r.t. the
ICM thermal energy density.
