Overview

Allow users to schedule posts before initially publishing.

Users

A long-requested feature from many users.

Implementation

Add a modal that appears upon pressing the Publish button, but before actually publishing. It should include a "publish date" section with the options to publish now or select a future date (just like we already do with Submit.as prompts).

Selecting a different date should simply set the created date to that time / date. Otherwise behavior doesn't change.
