annotate base/PlayParameters.h @ 47:bac8b14ab355

* Add menu for re-adding existing layers
* Fix layer tree window so that it at least approximates correct
* Add bundled operations in command history, for use with things like
  multiple consecutive changes to a parameter value
* Disambiguate plugins that happen to have identical descriptions
* Add spectral centroid plugin (could use some parameters!)
* Some other fixes
