Use both SCHPO (deprecated) and SCHPM (preferred) in the taxon checker

[selewis]

So that older GAF files with the previous taxon ID 284812 go through the same screening as SCHPM 4896: N=Schizosaccharomyces pombe

[selewis]

Actually there is a deeper problem.
pombe (4896) is a eukaryote (ncbi taxon 2759)
pombe does not have centromeres (GO:0005813)
but http://owlservices.berkeleybop.org/isClassApplicableForTaxon?format=txt&idstyle=obo&id=GO:0005813&taxid=NCBITaxon:2759
returns true

taxonchecker needs to preclude centromeres for eukaryotes

According to wikipedia, centrosomes evolved in metazoa: https://simple.wikipedia.org/wiki/Centrosome
However centrosomes have been described in Dicty: http://www.ncbi.nlm.nih.gov/pubmed/15548420
