New Karplus-Strong plugin

I'm currently working on a Karplus-Strong synthesis plugin called nekopluck. There's a very early version available at http://www.gjcp.net/svn/nekosynth/nekoplunk/tags/rel-0.0.1 for early experimenters. It's a hack on the nekostring plugin, and the GUI isn't really very functional.

This plugin is very much a proof-of-concept. A more functional one is in the pipeline (and indeed in Subversion trunk).
