comparison plugin/LADSPAPluginFactory.cpp @ 60:3086ff194ea0

* More structural work on feature extraction plugin C <-> C++ adapter
* Allow use of LADSPA/DSSI plugins with control outputs as feature extraction
  plugins (DSSI with MIDI output still to come)
* Reorder labels on spectrogram status box
* Minor tweaks in doc etc.
