• add a class attribute to script, link and style elements so that these can be checked for existence by a client-side script module loader
• remove bogus target="_top" from external urls; some of these "external" urls actually are absolute urls to the current site, mistakenly regarded as external; a _top target will stop angular from processing them
• allow HTML elements to contain dashes such as <my-html-directive>...</my-html-directive> ... these are entity-escaped otherwise.
