Final(?) netrik beta

We have released a new beta with a number of considerable improvements.

For one, window resizing is now handled correctly -- very useful if using in an
xterm.

Also, when waiting for a keypress before (re)starting the pager, now any key is
accepted, not only <return>.

A nice little feature is displaying the IP address of the connected host during
page loading.

Finally, there are a couple of fixes to the configure script -- this should
allow compiling in some constellations that failed so far.

There are no outstanding issues left now in the TODO for the first stable
release. If everything goes well, we will only proceed fixing new bugs found,
and release the final (stable) version in a few days or so.

This also means that all bugs still present now will probably go into the
stable, so if you know any please do report them. (Even if they seem obvious to
you -- nobody has reported them yet!)
