This builtin Keying Set is supposed to insert keyframes for every F-Curve that exists for the selected data (usually objects and/or bones only). However, as coded, it was only useful for objects, since it would just go through all the F-Curves for the object's action, instead of just the F-Curves relevant to a selected bone. Tweaked the code to make this case (and similar ones) hopefully work better by default.
