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.

With this convention, it's much simpler to identify whether an exception
has a custom template or if that template came from the rule itself.
This commit is a preparation for further changes.

Currently, we convert the properties of a rule into parameters and pass
them to the exceptions. That complicates things for a few reasons:
1. The exception knows too much: there's a lot of information in an
object, and the exception would only need a few parameters to work
correctly.
2. Any variable change becomes a backward compatibility break: if we
change the name of the variable type in a rule, even if it's a
private one, we may need to change the template, which is a backward
compatibility break.
3. The factory is bloated because of introspection tricks: it reads the
properties from the class, even from the parent, and then passes it
to the exception.
Of course, that means we introduce another method to `Validatable`, but
in most cases, extending `AbstractRule` is enough to create a new rule.

It's easier to identify the reason for choosing a specific message in
the rule than in the exception. The same goes for the key we use to
determine the templates.
This change will simplify the `ValidationException` because it will
already receive the template it needs to use. As a consequence, the
`Factory` also becomes more straightforward.

This change will bring many breaking changes. The good thing is that we
can finally use more modern resources available in PHP.
I can imagine that's not a popular change since it will bring many
breaking changes to users, but we shouldn't be stuck in time because of
that. Using some of those features will make it easier to contribute to
the project. At least, I hope so.
There are still some useless doc-blocks, and we're not using "readonly"
properties when we could. I aim to send those changes soon.

This commit will make sure that every class, interface, or trait will
have the "@author" annotation in it.
In order to create a list of authors, I used the "git blame" command,
which means that if someone changed or even created the file but does
not have any remaining line will not be shown in the list; it's a
trade-off worth but it is worth it. The other way to do it would be
carefully checking each file.

The "NestedValidationException" has exceptions that are its children.
However, we call them "related". This commit updates the term over the
library.
