0.6.0 emergency release

This release emergency release patches two important issues: (1) stale reification blank node generation, and (2) sticky broken semantic state after parsing invalid statements. You should upgrade as soon as possible and stop using any version prior version due to the risk of reification corruption and semantic query staleness.
