0.0.6+1

Minor bugfixes and improvements.

This release is a refactor. If we've done our job right, you shouldn't notice any large differences between this release and the prior release. Most of the work in this release is under the hood, to lay the remaining groundwork for basic Geists (https://subconscious.substack.com/p/scamper). Geists aren't part of this release, but should be part of a future release shortly.
