Nested element workflow improvements

[brandonkelly]

Description

When saving a nested element within a Matrix/Addresses field in card view, the changes are now saved to a draft of the owner element, rather than published immediately. The changes won’t actually go live until the owner element is saved. If the draft is discarded, the changes will be discarded too.

Nested element cards that contain unpublished edits identify themselves with a blue modified indicator. (Newly-added nested elements have a similar indicator too, now.)

This only affects Matrix/Addresses fields in cards view. Decided to keep element index view working as-is, since that view is more obviously dealing with separate elements that aren’t really “part of” the owner element’s content, like card view is.

CKEditor will be updated for consistency with these changes, as well.
