Synonym field to allow multiple entries per species

[n8upham]

Model this after the IUCN listing where they have a “Synonyms” field in their CSV output that includes data as e.g., "Abrothrix hershkovitzi|Abrothrix markhami|Akodon mansoensis |Akodon olivaceus |Akodon xanthorhinus”

So that is all recent name combinations as separated by pipes.

We can form that synonym pipes column using the 200k+ row listing that I sent you yesterday. Do you want me to work on parsing that, or are you already on it?
