Tags and Ratings

Tags are now working, you can click on the tags to do a quick search, or just type multiple tagwords to search for games. The tags that a game has are now displayed underneath the title on the game page, this way it's easy to find the same type of games quickly.

Also some work on the rating system for games, now showing the score in the top-right corner next to the name of a game. Only visible if a game has atleast one rating.
