- check implemented: responses are validated upon valid SL content (ErrorResponse, Create|VerifyXMLSignatureResponse) (ErrorCode 340)

- new errorcode added (340: unable to receive suitable response)
- default signature validation links changed (-> http://www.signaturpruefung.gv.at)
- recognition of non-textual objects: static switch implemented allowing to configure behaviour (at compile time) in case of signatures (default behaviour: skip detection of all signatures as non-textual objects)
- minor bug fixed: invalid evaluation of response charset resulting in invalid warn debug message
- configuration updated
- Default configuration updated
