spec file fix
make sure that the initialization functions can only be called once

starting omp cleanup -> needs to be brought to fortran to avoid problems
with clang
openmp code in executables removed and put into fortran code

it looks like LIBS will need to be set on Mac OS X to point to the location of
libopenmp, otherwise and build error will occur when linking the
xmimsim-cl.so
old net-line intensities treeview consistency bug fixed

and some spring cleaning as well
threshold for comparisons is now considerably smaller
Merge branch 'master' into xmsi2xrmc
