Version 2 0 0

[Robert-W]

See docs/MIGRATION_2.0.0.md for a complete list of breaking changes, new features, bug fixes, and things missing from the 2.0.0 release.

In summary, there are several enhancements here:

• generated code is finally a 100% plugin, no modification necessary to profiles or other areas to support things
• controllers are version specific
• handlers dont cast resources, making it easy to make them generic and move them out. They are now in phx-tools
• bundle returns are now consistently handled the same as all other resources. Previously, you had to cast all your entry resources yourself and then we would inject it into the bundle. You now need to create the bundle yourself
• All returned elements from services should now be case in the services, see docs/MIGRATION_2.0.0.md for examples.
• services should now return resources and not raw JSON, there is a new resolveSchema method to help with getting the version specific resources
• You can now return operation outcomes from your services to customize errors and error codes
• Added support for favicons
• enhanced logger api by providing access to winston's container api
• all files now lowercased so we could remove case correcting logic throughout the codebase
