CppTools: Add revisions to AbstractEditorSupport

So far revisions for AbstractEditorSupport were not needed because until
recently we only had a single snapshot ("global snapshot"). Now, since
editor snapshots are introduced, we need to make sure to update the
corresponding documents in these snapshots, too. To do this efficiently,
a revision is introduced for AbstractEditorSupport.
