1.1.0

• Added error property to the DocumentPaginator. This is used for failed
  requests otherwise it is null. When the request fails for any reason an
  ErrorBag is added with more information. Example:

CodebarAg\DocuWare\DTO\DocumentPaginator {
  ...
  +error: CodebarAg\DocuWare\DTO\ErrorBag {
    +code: 422
    +message: "'00000000-0000-0000-0000-0000000000000' is not valid cabinet id"
  }
}
