The main goal of this change was to make it easier to tell when a hierarchy has been deleted, but as a side benefit, it got rid of the use of PR_RESMAP. Also, it's easy to track the number of hierarchies. Unfortunately, it showed how brittle the component side of the ECS is (scene and canvas registries assumed their components were the first (no long the case), thus the sweeping changes). Centerprint doesn't work (but it hasn't for a while).
