Improved YouTube trailer matching accuracy

Browse Source 
Improved the trailer selection algorithm by requiring all game name words (normalized by removing apostrophes) to be present in the video title. Increased the number of processed matches from 5 to 10 and refined scoring bonuses and penalties, enhancing the accuracy for selecting the most relevant clip
