Created a Powershell script to package an official Ghost release for Azure, reducing 8 steps to 2.
Also changed the Azure configuration so that Ghost is secure by out-of-the-box, e.g. the intial sign-up / admin section is now https.

Also:
- Removed previous submitted azure package from /binaries folder. No longer required as previous versions can be generated by the Powershell script.
- We don't want our share our secret *.publishSettings or have .zip *.sha1 files that are created/used by the Powershell scripts.
- Added a Powershell script to deploy a package to Azure, uses Web Deploy and Parameters used for testing the Azure package using webdeploy
- Updated Readme.md with how to package a release using the Powershell script and testing on Azure.
