Title: fixed; no longer test non-required vals in string match

In the string `match` validator, there is no reason to test against null, undefined, or '' values as those
are validated in the "required" validator.

we'll no longer need to put extra checks in RegExps for null, undefined, or empty strings. if we want to validate these values we can enable the the `required` validator.

closes #934
