  1. Add ConjugacyClassesForSolvableGroup 

    .. and use it in two ConjugacyClasses methods: the generic one
for finite groups, and the one for permutation groups. Also merge
the two existing "generic" methods for finite groups (they had the
same rank, which is rather brittle).

This speeds up the computation of ConjugacyClasses for e.g.

    G:=WreathProduct(CyclicGroup(IsPermGroup,12), DihedralGroup(IsPermGroup,12));

from 110 seconds to 53 seconds on my laptop.
