Title: 2.3 doctype unified

A while ago the HtmlHelper method docType was defaulted to HTML5 (- html5: HTML5. Default value.)
For browser related output it makes sense to update the layouts accordingly.
Right now you would get the html5 doctypes for all sites, but on errors and 404s you still get the other one - using the default templates.

I didn't change the email templates yet - but at some point this might make sense to unify to the new standard, as well.
