before errors and outputs where ignored from the subscript and the main
script didn't fail nor did it output anything.
with this change the script properly outputs everything to stdout and
stderr. in the case the dylib script fails the whole script fails now.
the main function in dylib_unhell was kept since it can still be used
individually without the oscbundle script. the script had to be renamed
with an underscore to make it importable.
