add general replacement rules for SARAH-defined symbols
write real part of CKM matrix to SLHA file
write imaginary part of CKM matrix to SLHA file
add rounding function
read MODSEL flavour violation switch
add supported MODSEL flavour violation option 6
remove redundant SLHA input file entry
consider correct sign in rounding function
simplify reading of flavour violation SLHA switch
relax test precision on the flavour mixing Yukawa couplings

I checked that the difference in the Yukawa couplings (including
flavour mixing) between Softsusy and FlexibleSUSY stems only from
the different VEV used (see the comment in the code).
