comparison layer/WaveformLayer.cpp @ 76:45ba0b381c5d

* Fix long-standing off-by-1 bug in WaveFileModel that was getting us the wrong
  values for almost all audio data when merging channels (channel == -1)
* Implement cut, copy and paste
* Make draw mode work properly in time value layer
* Minor fixes to CSV import
