After troubleshooting configuration problems with several users, I believe I
have fixed the problem with the configure script that prevented some people from
building freqtweak. Anyone who had problems should definitely try the new
release.
Along with that, you get a 4096 freq bin mode, and a few tiny bugfixes.

I added a short example of how to pipe alsaplayer through freqtweak and out your
speakers without messing with JACK patchbays (see Usage Tips section).
