Add options to for example ignore broken links in html area or broken images

We could add hst:param's to hst:html tag to for example say something like:

<hst:html hippohtml="${document.html}">
<hst:param name="brokenlinkpolicy" value="ignore">
<hst:param name="brokenimagepolicy" value="ignore">
<hst:html>

or

<hst:html hippohtml="${document.html}">
<hst:param name="brokenlinkpolicy" value="text-decoration: line-through">
<hst:param name="brokenimagepolicy" value="/images/brokeniamge.gif">
<hst:html>

Or, a completely different approach would be, that we add a part in the hst:configuration for global policy..

For example :

hst:configuration/globalsettings

where we can configure how we like to treat brokenlinks in the frontend (remove <a> tag, or add some style like lin-through), and how to treat broken images.
