Rename 'Binding' to 'Slot'. The old term was causing all kind of confusion, and 'slot' was considered to be a better term for the intended functionality. This commit breaks existing blend files that were using the new layered Action for their animation. The animation data will be lost due to the rename, as there is no versioning code or DNA renaming logic. At this time the new system is still marked as experimental, so shouldn't be used for anything serious anyway. Pull Request: https://projects.blender.org/blender/blender/pulls/124170
