flamngo: Add site-dependend HTML-Parser

The flamingo-core HTML-parser does two things:

* remove the first <h1>
* re-write the HTML with beutiful soup.

First:
We want to leave our <h1> where it is since it is
places somewhere inside out HTML.
The Template should not be able to place it there...

Second:
BS-HTML is ugly!
