#4800 WBS: Add parameter track which is off by default (#4816)

* Initial WIP

* Identical results with spreadsheet

* Improved and more robust smoothing by filtering points first

* Improved smoothing and more GUI

* Include mixed-label for smoothing threshold

* Implement WBS parameters track

* Much better alignment of tracks without flickering

* Don't replace user description when dragging and dropping tracks

* Fix missing OBG and SH curves

* Fix curve and track D&D

* Make sure parameter curves aren't WBS curves
