Title: fixed configwriter to process post config (incl test and docu)

There is a bug in the configwriter which causes the problem that configured post-processor get ignored.
This pull request fixes this issue. See also #245

I also provided some docu about configuring post-processor and added a test case for that.

Feel free to merge.
