warn if Z3 == true and mu' or xiF are set non-zero
setting mu, Bmu, xiS at MX if SoftHiggsOut == true
bug fix: use NMSSM semi-sugra if Z3 == true to not constrain mS2
bug fix: inputParameters(53) is already a squared mass
adding check for <S> == 0 if SoftHiggsOut == true
bug fix: Bmu and xiS must trigger extended sugra

Since our (NMSSM) mSugra functions do not set Bmu and xiF, we have
to trigger an extended sugra condition if the user has set Bmu or
xiS to a non-zero value
