fix old bfo refs and update to ro

[wdduncan]

@gopi-kris @matentzn I've done a lot of hacking on the ohd-edit file. Two main tasks were:

• remove IRIs pointing to outdated versions of BFO
• change OHD classes to use RO relations

There is still work to do (e.g., migrate to UBERON for anatomical classes) ... @gopi-kris once this merged you will need to merge changes into the branches you are working on.
@matentzn Is this okay to merge?

List of commits

• remove gz files from git tracking
• update ecto import

• asser "part of (FMA)" to be subproperty of "part of"

• remove "Anatomical entity" as subclass of "material entity"; this caused reasoning errors b/c some anatomical entiteis were immaterial
• assert "anatomical space (fmal)" subclass of immaterial entity
