Disallow usage of <style> tag

Rule ID:

The <style> tag can be used to write CSS directly inside the document. When using multiple documents it is preferable to put all styling in a single asset and use the <link> tag to reference it to lower the bandwidth required (by preventing duplicated style across all page loads).
