Since the library doesn't need to give support to version 5.4 or less of
PHP using variadics in the constructor of "AbstractFilterRule" seems
better than doing the whole validation.
This commit will also apply the contribution guidelines to
"AbstractFilterRule" and use a better naming for it.

The "Digit" rule is meant to validate digits. However, by default, it
also considers any whitespace character (spaces, new lines, tabs, etc)
as valid.
Since the rule also accepts a list of characters to ignore during the
validation it seemed logical to me to leave the responsibility of
allowing whitespace characters on the hands of the one who uses the
rule.
The messages of the exception are not really consistent, this commit
will also fix that.
It's also clear that the "AbstractCtypeRule" is an unnecessary overhead
since it is only a proxy for "AbstractFilterRule". That one can and
should even be removed after this commit is applied especially because
this commit will also remove the method "filterWhiteSpaceOption" which
is the only substantial difference between "AbstractCtypeRule" and
"AbstractFilterRule".
This commit will also apply our guidelines to the "Digit" rule since we
want to do that to all the rules we have.
