protein targeting should be is_a localization

[pgaudet]

Right now we have it under 'protein transport', which is not correct, the targeting is separate from the transport. (We also need to look into whether 'targeting' is in scope for GO; usually proteins target themselves to a localization with a signal sequence, so their localization is mediated by another protein)

[pgaudet]

Removed comment on protein targeting: "Note that protein targeting encompasses the transport of the protein to the specified location, and may also include additional steps such as protein processing."

This is not correct. Targeting would be the steps before transport/import

• [x] removed all 'protein targeting' is_a 'establishment of localization', for all organelles
• [x] removed all 'protein import into an organelle' is_a 'protein targeting to an organelle'
