Move the reconciler into the lifecycle crate, so that we can (properly) support state changes. Wrap the reconciliation phase in a RenderEngine, which root-level objects (windows, etc) can subscribe to and interface with. Migrate a few things relating to themes out of alchemy core and into styles, because the reconciliation phase requires them and they fit well enough there... solving a circular dependency.
