Removes vocabs and propogates fixes for breaks (#79)

* Removes vocabs and propogates fixes for breaks

* Prettify diff: Undoing comment shuffles due to merge conflict edits

* 20% of time actual work, 80% prettifying diff

* Histories members -> poof!

We however have Histories in constructor, which we will remove out of the way
soon.
