Title: Add support for the Draft v4 multipleOf keyword.

Similar to Draft v3 `divisibleBy`, the Draft v4 `multipleOf` keyword basically does the same thing. It validates that the division of a numeric instance by the value of `multipleOf` is an integer. Implemented the functionality and removed the Draft v4 `multipleOf` tests from the list of v4 tests that are skipped.
