Change orientation of scp commands in commands.sh

[iannesbitt]

Since the only ssh direction that works is so[node|.test] > cn[|-stage.test], the scp command that is written to commands.sh should reflect that. Currently the command is:

scp mnlite@so.test.dataone.org:/home/mnlite/WORK/mnlite/instance/nodes/mnTestDVNO/xml/mnTestDVNO_PConzett.xml ~/d1_xml/mnTestDVNO/

It should instead be:

scp /home/mnlite/WORK/mnlite/instance/nodes/mnTestDVNO/xml/mnTestDVNO_PConzett.xml nesbitt@cn-stage.test.dataone.org:~/d1_xml/mnTestDVNO/

By default this will be run from a mnlite user account on the MN. At present the ssh user default is set to be based on the user that runs the script, i.e.

USER_NAME = pwd.getpwuid(os.getuid())[0]

will resolve to the current user (mnlite). In the future this will be configurable via #53 (to be e.g. nesbitt or another user).
