Diffusion: rough cut of history view

Summary:
Very very rough approximation of history view. I left out all the
log parsing stuff for now since we should be able to just look it up in
a Repository table and I think that'll be a bit faster, although we can
muck around and see.

Test Plan:
Looked at history of a path
