Fix for ignored timeout problems in AS2Send
- A timeout while uploading data between client and server was not registered by AS2Send.exe/as2send.sh. This caused in this case the creation of a send job of a file with 0 bytes and the return code was still 0. This is now corrected - in case of a timeout no send job is created and the return code is 1, furthermore a corresponding result file is created if the parameter "-response" is set.
