* Changing to the ShapeKey editor now automatically enables the value sliders * Filtering code for ShapeKey editor can now do AnimData block filtering too (internal details...) * Silenced console warnings when inserting keyframes on F-Curves with no keyframes already (for Animation Editor sliders) * Made the update code for keyframe transforms send more general depsgraph updates. Unfortuately, this still doesn't resolve the update problems with shapekeys
