New version of nekobee

I've just uploaded a new version of nekobee. I fixed the excessively loud output (roughly five times louder than say hexter) which caused a few problems, modified the output to have an atan waveshaper to give a bit of distortion (and provide a quick fix for the output going crazy at high resonance settings), and tweaked the filter code to more accurately reflect the "kind-of-18dB/oct" filter shape. Grab it, try it out, and let me know how you get on. Download it either from svn, or grab the tarball
