Description and Documentation
Change TWiki's link style to: 1. remove the question mark link behind a wikiword, 2. use a color and style similar to Mediawiki to indicate a non-existing page. Hovering over a non existing page link should show a tooltip with the name of the topic followed by text "(this topic does not exist)".
