Release 2.2.1

Two bugfixes with one being critical (caused segfault, sorry for that)

• pcap-thread had an issue that threads where not closed on exit of pcap_thread_run(), this only created many threads in my testing environment but reports came in that it segfaulted.
• When started dsc (not in debug mode) it will wait to align with the time, that did not get update with the configurable interval change.
