Yet another iteration from UX on how roots should be ordered. Since we no longer categorize by type, remove from public API. Updated asset drop with new dividers. Update public API docs to be explicit about required columns. Hide flags and columns that aren't required for third-party apps. Move remainder of potentially blocking work to AsyncTasks, including creating directories, picked root resolution, and creation of new documents once picked. Improve performance of layouts by removing baseline alignment and reduce hierarchy depth. Set alpha on ImageViews directly to avoid offscreen rendering hit. Limit returned recents to 45 days. Show load in recents when still waiting for backends. Show empty message when no recents stacks to create from. Use unique key when saving recent stacks.
