confirmation

Provides a developer API to handle any kind of confirmation.

- It assumes that user gets a confirm link over some channel (usually email, but may be any other).
- It allows to confirm or reject.
- It may or may not have an expiration time.
- It provides only the core logic, any domain specific logic happens in a bundle class.
- Also all domain specific data will go to fields of that bundle.

See the confirmation_example module and tests.
