Title: MAINT:Change ontology term identifier to bigserial

The term identifier in the ontology terms table was set as a big int, thus
adding new user-defined terms was cumbersome, with this change in place those
the term is now a bigserial.

I have also changed the ontology file in the beast, so people WILL HAVE to
reload their databases.
