Bugfix [#25990] backward compatibility with ShapeKey Actions :: 2.49
-> 2.50
Actionified ShapeKey IPO-blocks (i.e. "Shape Key Actions") would have
an action channel with the hardcoded name, "Shape", and this action
would be assigned to Object level (although ShapeKey blocks had their
own IPO-block slot, only Objects could have actions, so actionifying
ShapeKey IPO-blocks would wrap a ShapeKey block's IPO's to an Object-
level action).
Hence, the path conversions code would wrongly interpret this action
channel as referring to a Pose Channel instead, thus creating some
invalid paths with a 'pose.bones["Shape"]' prefix wrongly getting
tacked on. To ensure that the converted animation can work out of the
box, a 'data.shape_keys' prefix is now used instead so that these
actions can still be Object-rooted while still being able to correctly
control the Shape Keys. This is because there's no easy way to
identify and then shift such action from Object-level to ShapeKey-
level within the conversion code. The consequence though is that such
converted ShapeKey actions CAN ONLY BE USED THROUGH OBJECT LEVEL (i.e.
via Action NOT ShapeKey editor).
Secondly, the Action/ShapeKey editor version patching code has been
modified so that if a ShapeKey editor view was active when loading an
old 2.4x file, the action gets cleared from the view. This is because
of this didn't make semantic sense: the ShapeKey editor is for
ShapeKey-rooted actions, while the Action Editor is for Object-rooted
actions. The converted files though let Object-level actions be shown
in either one.
