• Field validation (#369)

  Introduces two new Field options available for every Field: required and
  validate. The required option will make sure the field value is not empty
  when saving. The validate option can be used to validate the field value
  using a custom function. The function should return true if the value is
  valid, false if it is not valid and a string if it is not valid and a
  message should be shown to the user.

  alinea.text('Hello field', {
    help: 'This field only accepts "hello" as a value',
    validate(value) {
      if (value !== 'hello') return 'Only "hello" is allowed!'
    }
  })
