Slightly tweaked game page

Just a slight update to the game page for Far From The Tree. 

• Title logo now appears behind the WebGL play window (and play button). Before, the logo wasn't on the page.
• Changed cover image to an animated GIF. This reduced the initial quality, but helps show off the game beforehand.
• Changed the tagline to one that better describes the game itself.

I am also proud to say that this has become the best performing game on my account as of date. Brandon, Chad, and Sam all worked really hard on this game, and we all appreciate the reception and feedback to the game! Thanks!
