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.
Merge pull request #29 from dennisroche/master

Scripted the Azure packaging of Ghost and optimised the deployed configuration
Added external dependency on Ionic.Zip as the System.IO.Compression.FileSystem created an archives that wasn't able to be read by WebDeploy and assumably Azure Web App gallery.
Clean-up temporary packaging files at end of script, unless -Debug is specified.

Pop-Location if there was an error.
UTF8 output from npm was causing the Powershell console to crash (however not the Powershell ISE), so strip out UTF8 characters using regex.
Merge branch 'master' into PublishForAzure
