Add suppress_output parameter in create_or_update_organism.py

[MoffMade]

Based on galaxy-genome-annotation/python-apollo#40, I'd like to update the Create Or Update Organism tool to make use of the returnAllOrganism paramter in the add_organism call, to reduce the time taken when the apollo instance contains a large number of organisms.
