- Remove Blueprint::all()
- Add Blueprint::in() to get blueprints in a directory (namespace)
- Blueprint::find() can look in a directory
- Top level Blueprint CRUD is removed (except listing which will be repurposed) and added to Collections (eventually will get duplicated onto Taxonomies, Globals, Forms, etc)
- Collection entryBlueprints read from the directory instead of needing to be defined in its YAML file. The method is now only a getter.
- Remove editUrl and deleteUrl from Blueprint because it complicates things now that it'll be different depending on the usage. Just use the route helper.
- The "Links" toggle on the edit collection page will create/delete a link.yaml (not entry_link) blueprint, rather than add to the blueprints list.

…ns/blueprints/edit, taxonomies/blueprints/edit, etc.

- GlobalSet@blueprint is just a getter
- Global Variables@fallbackBlueprint uses array_values because it shouldn't be keyed by field handles
- Title is not required on a global set's blueprint because there will always be one. It's unnecessary. Move the validation inline for the collection and taxonomy controllers.

- Remove PublishBlueprint route and controller. The asset editor was the only one that was using it. Just bring the blueprint directly into the resource now.
- Removed the fallback asset.yaml and hardcode it right into the AssetContainer class.
- Blueprint::makeFromFields() calls values to prevent them being keyed by handle.

Also closes #2008

- Clean things up using ExistsAsFile trait.
- Remove the fallback directory. Instead, bind fallbacks into the repo with closures.
- Blueprints can have orders defined inside the yaml
- In memory caching has been removed temporarily from blueprint repo. This will be redone nicer.
