Add text flow history to activity panel.

Description

The old GWT editor can show history of text flow revisions, and copy any of the revisions to the editor. This or equivalent functionality should be added to the React editor, based in the activity panel.

In short, a copy button should be added to each ActivityFeed item since the text history is already designed into the Activity Tab
