Draft Mode in Studio

Ability to save drafts that can be viewed separately to the published page.

Also need to look at a User Role for publishing so that certain users to do edits in draft and another approves and publishes (would need a button to submit a notification to the publisher).

When loading a page that has at least one draft, we should present the user with a preview mode which lists the current version (omitted in screenshot) and the saved draft versions below.

We propose adding an additional button to the editor to save as draft.

When clicking on one of the drafts, it will preview in the frame.

The user can then edit the draft to open it in the main editor.

Once the user publishes that draft, it should be removed from the studio_drafts array.

Other drafts in the list should then turn light red, to indicate that they are out of date as their created_at date is less than the last publish date of the page.

In this drafts view, you should also be able to rename (default is just draft), copy draft and delete draft. (Reorder is redundant).

We should also be presenting the user who created the draft under the name & date.
