comparison plugin/FeatureExtractionPluginFactory.cpp @ 117:c30728d5625c sv1-v0.9rc1

* Make vertical scale alignment modes work in note layer as well as time-value
  layer, and several significant fixes to it
* Make it possible to draw notes properly on the note layer
* Show units (and frequencies etc in note layer's case) in the time-value and
  note layer description boxes
* Minor fix to item edit dialog layout
* Some minor menu rearrangement
* Comment out a lot of debug output
* Add SV website and reference URLs to Help menu, and add code to (attempt to)
  open them in the user's preferred browser
