Refactor Validators

[zhorton34]

• Include validator from 'vuejs-validators' as a dev-dependency

• Automatically apply validator logic/macro methods when rules() method is used.

• Replace validatable parameter
  Was: form(validatable, data).rules(...)
  Now: form(data).rules(...)

• Replace form.getErrors() method
  Was: form.getErrors()
  Now: form.errors()

• Replace form.getValidator() method
  Was: form.getValidator()
  Now: form.validator()

data: () => ({
  form: form({ 
        name: 'zak', 
        email: 'zak@cleancode.studio' 
    })
    .rules({
         name: 'required|min:5',
         email: 'required|email|min:8'
    })
    .messages({
        'name.required': ':attribute field is required',
        'name.min': ':attribute must have at least :min characters',
    })
});
