change the automagic import folder change to s3n when tests are run using clouds built with ec2_cmd.py on aws (jenkins)
make it s3 like it was in the old days. I should change the import s3 to import at the folder level like s3n now since we soupport that now in h2o

this should only effect jenkins or people using ec2_cmd.py and running python tests on amazon ec2
    # cfg['redirect_import_folder_to_s3n_path'] = True
    # kbn 9/28/14..change it back to s3 to see what breaks
    cfg['redirect_import_folder_to_s3_path'] = True
Merge branch 'master' of github.com:0xdata/h2o
