Hashing consistency concerns

[arrdem]

@arrdem isn't the use of hashCode for obj hashing brittle in shelving? If I recall nothing guarantees it'd be consistent across runs of the same app.

Max was also kind enough https://github.com/replikativ/hasch, which seems to provide a consistent SHA512 -> UUID over Clojure datastructures. Definitely worth looking into this, and more likely than not just throwing out my own content hash implementation.
