conserver-8.1.20 is available

I've finally integrated and expanded a patch that was submitted over
3 years ago (yikes!) - direct IPMI serial over LAN support.  Hopefully
this will work just as well as forking off an ipmi command but also
allow less resource usage.

I'm curious to hear about any success or horror stories - share if you
can.  Thanks!

version 8.1.20 (Apr 4, 2014):
        - IPMI serial over LAN support via FreeIPMI - based on patch by Anton
          D. Kachalov <mouse@yandex-team.ru>
        - minor cleanup of code, removal of gcc warnings and such that should
          have no fuctional change
