This CL substantially refactors folders to be able to take contents of type AppPairInfo. App pairs can now be moved in and out of folders, and launch from folders.
This CL contains only logic and model changes; animation and style changes (for dropping items into folders, color changes to app pair surfaces, etc.) will be in a following CL. Another CL (hopefully) will contain tests. I'm planning to submit them together, but this patch should also be able to stand alone with no issues (except janky transitions).

Previously, app pairs and folders shared a common data model, FolderInfo. Now we need to separate them, so a new type, CollectionInfo, will serve as the parent of both types.
