Sitecore Stuff and Such

1. Provision Sitecore to Azure if Sitecore is not present
2. Stop the Content Editing Site
3. Cleanup before deploying the application
4. Deployment of the application itself
5. Start the Content Editing Site
6. Hold on a moment for the CM to get alive
7. Sync your Unicorn stuff
