Improve the weighting of the search search results
As a visitor I want to get relevant search results AC
- Pagetitels should get a bigger impact
- Show events only of future dates
- Make news articles less relevant, if they are older
Test Cases:
- "Board" should point at first result to https://typo3.org/project/association/structure/board
- "features" should point to https://typo3.org/cms/features
