Tracking what you have looked at ..

[Phil Race]

As the number of CSRs in process increases I am starting to realise that
it is not so nice to track what I have looked at and OKed and also whether
it was OKed for provisional or final.
Adding yourself as a reviewer is non-specific
Making a comment is not intimately tied to a state.

I think we need some explicit fields that correspond to per-person and 
state.
This may not be easy in JBS but that should not change its importance.
