PHREEQC: Changes to implicit Nernst Planck calculations for electro-migration.
Concentration-oscillations in 3 cells at the column boundary are now dampened,
which improves the stability of the calculations.

PHREEQC: A new Basic function DEBYE_LENGTH was added to return the
value of the Debye length, typically notated kappa^-1. The value is
related to the decay of the surface potential with distance from the
surface. Theory says that the potential at distance d from the surface
is equal to psi0*exp(d/DL), where psi0 is the surface potential and DL is
the Debye length. The lengh is inversely related to ionic strength.
Example:
10 DL = DEBYE_LENGTH

KINETICS_RAW, or KINETICS_MIX. Now, the correct proportional relation should
be maintained if the moles in EQUILIBRIUM_PHASES or KINETICS are changed.
An error message will result if, for example, EQUILIBRIUM_PHASES is modified
to remove the phase that EXCHANGE is related to.
