use simplejson in python2.4
keep track of original LD_LIBRARY_PATH when running modulecmd, things might otherwise break
code cleanup in modules.py
actually use the entire os.environ, we use Popen anyway
Merge branch 'develop' of github.com:JensTimmerman/easybuild-framework into develop
only keep track of ld library path, since we can change other things in the environment for the better (like modulepath)
correct authors
don't dump whole environment every time modulecmd is called, only show adjusted LD_LIBRARY_PATH
fix debug log msg if LD_LIBRARY_PATH is not defined in original environment
