When converting an object into an array, we exclude the message root
message from it. Since we're using a convention to template those
messages as an array, we could also use the same convention to return
those messages.
While working on it, I noticed that the name "__self__" wasn't
reflecting what that really meant, so I renamed it "__root__" because it
better reflects the meaning of those messages/templates.

There are a few "problems" with the current engine:
- Allowing each rule to execute assert() and check() means duplication
in some cases.
- Because we use exceptions to assert/check, we can only invert a
validation (with Not) if there are errors. That means that we have
limited granularity control.
- There is a lot of logic in the exceptions. That means that even after
it throws an exception, something could still happen. We're stable on
that front, but I want to simplify them. Besides, debugging exception
code is painful because the stack trace does not go beyond the
exception.
Apart from that, there are many limitations with templating, and working
that out in the current implementation makes it much harder.
These changes will improve the library in many aspects, but they will
also change the behavior and break backward compatibility. However,
that's a price I'm willing to pay for the improvements we'll have.
