build warning: bnlcrl.utils: module references __file__

[robnagler]

This code is suspicious:

    script_path = os.path.dirname(os.path.realpath(__file__))

    # Fix for Jython:
    try:
        script_path = script_path.replace(
            os.path.join(format(os.environ['HOME']), '.jython-cache/cachedir/classes'),
            ''

I'll try to change it to the resources. Jython fix is not necessary anymore since there are lots of python libraries to import and Jython will probably not be used anymore.
