examples/module.mk: fix compilation condition

Compile lattice_fmssm_fmssmn.cpp and
lattice_numerical_fmssm_fmssmn.cpp only if $(FSCONFIG) --with-fmssm
and $(FSCONFIG) --with-fmssmn are both yes.
Merge branch 'master' of ssh://pktlogin.phy.tu-dresden.de/soft/users/theory/FlexibleSUSY
specialize block comparison to GAUGE only
Fix build error of examples/switch_MSSM.cpp
Hide method-switching examples

Hide make rules for switch_MSSM until the interface matures to avoid
build errors.
