Introduces new simulator, task inspector & auditor components

[colinhicks]

New (or refactored) components:

• Simulator: UI controls for executing the linked job.
• Graph: swapped engines; richer UI interactions available.
• Job inspector: Shows env summary for the selected task on the workflow graph.
• Auditor: Displays compilation errors and spec validation status for linked components.

Selected data structure changes:

• All core component types use the blueprint ns. Om components and queries are now dispatched by the full :component/type value, rather than by the type ns.
• Components now render a span with the text value of :content/label when configured.
• :evaluations/link migrated to :link/evaluations.

A good way to see changes in context is by looking at the showcase.cljs diff. As before, rendering the showcase in your browser is the best entry point for seeing what's possible and how things work.
