adds some QC checks to the SEPIO pipeline to avoid errors in the future
Fixes some errors:
Changing the license to CC-BY 3.0 (what it is)
Removing obo:OBI_0000938 and obo:OBI_0000999 from SEPIO, both of which are obsoleted. We should never ever obsolete someone else's classes, even if they are obsolete within SEPIO. This is called injection and makes it impossible to use SEPIO with other ontologies! Just delete classes you don't need anymore if they are defined in other ontologies, and obsolete only the ones defined in SEPIO.
Adding a bunch of owl:deprecated annotations
Fixing a few minor annotation bugs (whitespace, capitalisation, wrong property)
