Major Description
Currently Click supports HTML imports by overriding the method #getHtmlImports.
This method is string based which makes it difficult to support advanced features such as templating, conditional imports, resource versioning etc.
This feature request proposes to introduce first class HTML header resource classes including Javascript, JavascriptImport, CssImport and Css.
Further a new method should be added to the Control interface: 'public List getHtmlHeaders' which returns a list of the Page or Control's HTML HEAD entries.
This makes it possible to modify the Javascript and CSS imports without overriding a Control.
