Fixes #99

**Snapshot Actions: **

1 - Hit "Publish" Button

• Publish ( Without Confirming )

2 - Select "Publish” from dropdown

• Confirm Publish.
• If clicked again
  • Publish.

3 - Select “Save Draft” / “Save Pending" from status -

• Change changesetStatus to draft / pending.
• Save as draft / pending.

4 - Hit “Draft” / “Pending" button

• Save as draft / pending

5 - Select “Schedule” from dropdown

• Show the edit box
• If date is of future
  • Change changesetStatus to “future”
  • Save changeset.
  • If title/date is changed.
    • Auto Save title/date entered.
• If date is not of future
  • Show notification to change date to future.

6 - Auto Save happens from core

• If current status is publish
  • Save as “auto-draft” ( by default )
• If current status is pending / draft
  • Let the changeset save as the current status ( pending / draft )
• If current status is future.
  • Save with future date
  • If the selected date is not of future
    • Save changeset to the previous future date used.
• If “Confirm Publish” is the text in button.
  • Save changeset to the current status ( pending/ draft/ future ).

Issues:

• When selecting “Publish” from the dropdown, the button changes to “Confirm Publish”. If you then click in into the preview or allow the autosave logic to run, then it goes ahead and publishes even though you never click the button. Additionally, the changeset UUID doesn't get removed from the URL.
