Add publishedAt field for video model.

* New field added in the `video` table + migration script

* `publishedAt` updated to NOW when privacy changes from private to
  public/unlisted (default = NOW)

* Models updated to handle the new attribute

* Client interface updated to use `publishedAt` instead of `createdAt`
  except in My Account > My Videos view
