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
