The mime-util library contains two content type mappings for .css files: application/x-pointplus and text/css. Unfortunately, using the wrong one will result in most browsers discarding the file as a CSS file. Ensure we only use the correct type for CSS files. This happens because MimeUtilFileTypeRegistry attempts to get all MIME types from mime-util and then sort the result based on the specificity of each type. Since both types have no magic string, only the ExtensionMimeDetector matches. Change-Id: Idfe88dc823f191d9c9e0b9c9da3b5d2ec471f9db
