dsc client HTTP Timeout

When joex and co. are too busy, the HTTP upload(s) of the dsc client (upload and watch) can time out.
This behavior leads to missing documents either by skipping the upload(s) or by aborting the whole process of uploading multiple files.

A workaround can be used by using CURL and using the parameters "--max-time" and/or "--connect-timeout"
