Move core rules into the "Core" namespace
That helps organize the code better, making it easier to spot the core
rule. It also helps not allow the Factory to load those rules, as the
new namespace is not registered in it.

Note that the "AbstractAge", "AbstractRelated", and "AbstractRule" were
not moved. I want to do that only when I refactor them.

After I moved classes, I realized that "Comparison" and "FilteredString"
had no tests. I created the tests, and while I did that, I spotted two
bugs:

* The "Equals" rule was failing when comparing non-scalar wth scalar
  values;

* The "Equals" and "Identical" rules were not working correctly because
  "Comparison" was converting their values.

I fixed those bugs in this commit.
