Proposal to Digit validator

[davihu]

It would be nice, when Digit validator can handle integer as well as string value. I enabled orm.cast_on_hydrate and all Digit validations are now triggering an error because of int types :)

Please change actual behavior to

if (is_int($value) || ctype_digit($value)) {
  return true;
}
