[Validator] forced all validation annotations to be in the validation namespace to avoid collisions, removed the need for the wrapping @Validation annotation

Before:

    /**
     * @Validation({@DateTime()})
     */

After:

    /**
     * @validation:DateTime()
     */

The @validation:Validation() construct is not needed anymore (it is still supported
as this is useful when you have several annotations with the same class).

So, the above is equivalent to:

    /**
     * @validation:Validation({@validation:DateTime()})
     */
