* Set content type for azure blob storage.

Without content type set website hosting (see https://azure.microsoft.com/en-us/blog/azure-storage-static-web-hosting-public-preview/) doesn't work correct (browser download all files, including .html instead display it).

* Change normalization to support multimodule projects.

In multimodule project resourseName starts with double dot (e.g.
../moduleName). FilenameUtils.normalize converts such paths to null and
causes NPE.
