2005-09-08: news scheme implemented

A general scheme for handling news messages was implemented:

• The summaries of the two most recent items always appear on the front page.
• More (ten) are visible on the [:News] page. And there's a [:News/All] as well.
• Below each summary, there's a link to the full message.
• On the [:News] page, there's a form to conveniently create new messages compliant to the the naming and structuring conventions:
  1. enter a short descriptive title
  2. click on "Create"
  3. work with the template you get.
