Non-recursive conversion

Entity conversion no longer recurses on arrays

Cljs 844

Bumped dependencies

IO operations

Added new io operations

Entity keys

Entities are no longer restricted in key type

Removing Cheshire

Dependency on Cheshire is removed, and converting entities to triples is quieter

Lookup refs

Added lookup refs into entities

Expanded query types

Queries can now resolve to types that occur outside of the original restrictions

Entity node types

Entity nodes were previously only keywords. This release allows for other node types.

Bugfix for multigraphs

Fixed an error caused when multigraphs tried to add the same value multiple times to entities

Clean artifacts

The generated jar used to have ClojureScript as an unnecessary dependency. This has been fixed.
