* Adds assets to the page

* <link href="some/resource" rel="something" type="some/mime" />
* <alternate href="some.rss" type="application/rss+xml" title="RSS Feed" />

* If any href is a simple string (i.e. no ${...} expression), and it is
* relative, it will be passed to CurrentPath->url->down to form an

* Full gory attribute details:
* script: a HTMLPageScript asset
* href string required
* type string optional default 'text/javascript'
*
* stylesheet: a HTMLPageStylesheet asset
* href string required
* alternate boolean optional default false
* title string optional default null
* media string optional default null
*
* alternate: a HTMLPageAlternateLink asset
* href string required
* type string required
* title string optional default null

* link: a HTMLPageLinkedResource asset
* href string required
* rel string required

* title string optional default null
