Mass or batch user create

As inspired by http://plone.org/documentation/kb/batch-adding-users

The format I used is simpler:

Kim Nguyen <nguyen@uwosh.edu>
Joe The Shark <joetheshark@uwosh.edu>

The script I used:

# Create new members with properties supplied from a CSV file.
# The script expects a File object with id `users.csv` in the same folder
# it resides.
#
# The format of the CSV needs to be:
#
# name;email
#
