Sfermion d.o.f. fixed in 1-loop effective potential of VhAtMin() of
nmssmsoftsusy.cpp.  Also fixed 1-loop factor (32 * pi^2) --> (64 * pi^2)
Fixed d.o.f. for charged Higgs in 1-loop effective potential of VhAtMin().
Included 2-loop prefactor alpha_s / (16 * pi^2) and split apart fermions
to avoid mixing up with 1-loop contributions.
Changed wording of flagHiggsNoMin(true) to reflect the true situation of not
expanding about a global min.  Noticed that default slha2 input file
nmssmSLHAZ3Input now triggers global min flag.
nmssmmanual.tex: added description of NMSSMTools flags for MICROMEGAS and NMSDECAY
Tweaked values in Block MINPAR of nmssmSLHAZ3Input to avoid flagHiggsNoMin(true)
begin triggered.  Same for nmssmSLHAnoZ3Input, but also had to tweak
Block EXTPAR to get a suitable minimum.
Merge branch 'vhatmin' into nmssm2
moved the non-perturbative test on lambda and kappa to be separate
from other Yukawas and weakened the condition to sqrt(4pi).
nmssmsoftsusy.cpp conflict resolved and merged.
