Cleanup of the omero-setup from redundant stuff

This is the avaited cleanup. 
  - Deleted all the duplicate auto_importP.py and *P.users and *P.inc and similar, leaving just one auto_import.py and .inc and .users (might need this routine yet).
  - Put the small testing images into a special directory.
  - Renamed the examples for the auto_import_directory.py (=Colin's newest script)
  - Deleted the rsync files except one
  - Deleted the inc and exc files - these were created just for the very first draft by Josh and are replaced by the auto_import.inc file

Everything else should be left at peace as it was by this PR.
The idea is to use mainly auto_import_directory.py in the future.
