Better module distribution

[fastner]

Today both modules

import VuexValidator from "vuex-validator";
import BaseValidator from "vuex-validator/lib/BaseValidator";

are used. The latter one has a lib component in path. This is ugly. Maybe both modules should be exported by vuex-validator.

import { VuexValidator, BaseValidator } from "vuex-validator";

or

import vuexValidator from "vuex-validator";
const VuexValidator = vuexValidator.VuexValidator;
const BaseValidator = vuexValidator.BaseValidator;
