    EPlugin: new util function for creating an EAlert from GError
    
    * we use GError for error propagation
    * errors in Evolution are displayed via
      EAlertBar instances, which take EAlert
      instances for displaying
    * the util function creates a very basic
      EAlert instance from a GError
