To make the code, especially that of actions, easier to read and maintain, the generation of pages should be based on HTML widgets:
 * `MoinMoin.widget.htmlpage.Document` - a HTML page, including HTTP headers
 * `MoinMoin.widget.htmlpage.Head` - header 
 * `MoinMoin.widget.htmlpage.Body` - body

This also eases the setting of special headers, while keeping the ability to stream pages (or recognizing the error condition that code sets headers ''after'' we flushed them already).
