MTB-GOA version 16

As promised, this update contains the other half of the "processes for every activity" fix. It also has a few other fixes, additions and missing papers, so it's worth updating otherwise as well. This is probably the last big semiautomatic fix, and maybe the last big error fix for this database. From now on fixes will likely be done by paper review, which is a slow process. The other fixes to be done are frequent specialization of annotations, esp. whenever the GO hierarchy changes. This also means we now have time to expand the database scope---about which details in a later post!
