annotate widgets/PluginParameterDialog.cpp @ 62:50429a56680f

* Add plugin parameter dialog, and use it to set up parameters for feature
  extraction plugins via a semi-opaque (translucent?) configurationXml string
  which is associated with a given transform instance.
  This is not yet saved to and restored from the SV file properly.

* Remove no-longer-relevant BeatDetect and BeatDetectionFunction transforms
  (replaced a long time ago with the beat detector plugin).
