Adding Folder specific change types

While designing some features using Folders, and checking if I could use AUDIT_DETAILS to store logs for Folder changes, detected for Folders the current change type terminology (for AUDIT_DETAILS.change_type: DV_CODED_TEXT) might not be appropriate.

For instance, on my design I need to log when an item is added or removed from a Folder, and separate both cases. Now I can use "modification" as change type but it doesn't have the required granularity.

I would like to propose adding new change types for Folders:

+ addition: one or more items or subfolders where added to the folder
+ removal: one or more items or subfolders where removed from the folder

For other actions, the current terminology is enough, like "creation" and "deleted"
