GNUnet 0.4.1 is there!

I've just packaged GNUnet 0.4.1. It's mostly a bugfix release, but it also 
has some nice additions, most notably that the hostlist is now downloaded 
from ovmj.org automatically on startup (the URL can be configured and anybody 
who can run an HTTP server could put up another hostlist, so it's not 
hardwired in any way). This should make the initial installation and use much 
easier.

Since we had the wrong endianess in the port-number, the protocol has 
(unfortunately) changed again slightly, breaking 0.4.0 compatibility. Also, a 
couple of segfaults and other problems (e.g. in the build process) were fixed.

On a related note, libextractor has been improved further, now supporting 
keyword extraction from real, png, jpeg, html, gif, mpg and ogg formats. It 
is highly recommended that you install libextractor (and in fact required for 
the rpm). There is now also an RPM for libextractor on the libextractor 
webpage (http://www.ovmj.org/~samanta/libextractor/).
