The maxlength validator (https://github.com/pagekit/vue-form/blob/master/src/validators.js#L51) fails when no value is provided. No value should be a valid value when maxlength is applied.

It would be nice to let the vaidation of minLength and maxLength [validators](https://github.com/pagekit/vue-form/blob/master/src/validators.js#L47) optional by passing in 0 for the arg. This way it can be set dynamically more easy....
