Release script for automating releases

Added a deploy-release.sh script that does almost everything in the release template automatically. Outstanding issues is uploading and modifying files on S3.

All scripts has been moved to tools-dir.

Going forward this should ideally be executed on Jenkins and possible split into smaller scripts for easier management there.
What changes should we make. The current release template also just says to copy all the documentation?

Also 2 lines further down I update the description to match the new version number. It is slightly misplaced though.
