Want to use now zmq for all communication between the server and the
client, already introduced lots of works, seems still a bit hakis, since
i implemented my own logger as well now, but well it seems working quiet
well already, very fast indeed except the startup.

TODOS:

* input and output must be read/written by client otherwise the server
  can't sit just anywhere, maybe to difficult and not useful but let's
  see
* configuration file and pidfile and so on should be handled in a more
  reliable way, including storing of the pidfile in the configs
  directory and not in tmp
it is quite big and the main things are still not really better, logging is a mess, but restarting works with a heck
improved source code fatching, now doesn't need meta anymore should be much more reliable and faster now
