Update game detail UI to eliminate white space

[willcravitz]

As of right now there are two horizontal sections on the game detail page. Top contains the image on the left, then game title and minor details on the right. Bottom contains nav links and the information section. This results in a large blank gap on many games pages. The UI should be updated so as to display all game information underneath the title to prevent this gap.

These issues and the proposed solution are described in more detail in this PR review #288 (review).
