Radium 5.1.5 released

[kjetil]

Changes 5.1.4 -> 5.1.5:

• Audio: Fix adding undo entries when parameters are changed in the
  native GUI of a plugin. Sometimes a lot more than 1 undo entry
  was added per second. (This functionality is still not working
  perfectly though.)
• OSX: Workaround for a bug in a 3rd party library that caused lots
  of undo entries to be made when when creating and deleting
  AU plugins in certain situations.
• OSX: Fix a bug the in keyboard handler that sometimes made Radium
  crash. Seems to be related to using non-latin keyboard.

• Audio: Ask "Are you sure?" when trying to load a Moody Sampler 5.0
  VST plugin instance. This plugin crashes when it is deleted.
• Audio: Don't crash some VST plugins when undoing a deletion.
• Editor: Make the horizontal track slider more conventional.
• Build: Include initial LLVM 5.0.0 support from Faust2 (Teteros)
• API:
  • New functions: getTrackSliderScrollerX1, getTrackSliderScrollerY1,
    getTrackSliderScrollerX2, getTrackSliderScrollerY2,
    setTrackSliderIsMoving, getTrackSliderPos, setTrackSliderPos.
  • Renamed setScrollbarIsMoving to setEditorScrollbarIsMoving.
