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

*
|
|
* 1. Regardless of how many slot caches are rebuilt, this function will need
|
|
* to loop over all IDs anyway.
|
|
* 2. Deletion of IDs may be hard to detect otherwise. This is a bit of a weak
|
|
* argument, as if this is not implemented properly (i.e. not un-assigning
|
|
* the Action first), the 'dirty' flag will also not be set, and thus a
|
|
* rebuild will not be triggered. In any case, because the rebuild is global,
|
|
* any subsequent call at least ensures correctness even with such bugs.
