Graph Editor: Bugfixes for option where only the keyframes of selected F-Curves are shown

* Selected keyframes in unselected F-Curves were still being modified, although not shown
* Selection tools for keyframes were changing the selection status of F-Curves, making keyframes sometimes disappear after trying to select another keyframe

* Warning fixes in a few other files
