this patch adds (actually fixes) hexenworld rcon support for
xqf. It applies to both xqf-1.0.5 and to the latest cvs snapshot.
The rcon support is fixed by adding the latest huffman encoding
and decoding routines from the uhexen2 project: sending the message
doesn't actually need any encoding but if the received message isn't
decoded, garbage is displayed especially for long responses.

this patch is also submitted to the xqf project. see the xqf patch
tracker entry #1806181 at:
http://sourceforge.net/tracker/?func=detail&atid=313296&aid=1806181&group_id=13296
