resized bootanimation for 480x800

Hey there. You can omit the commit for d2 support, just thought I'd let you know that I have resized the jellybeer bootanim for 480x800p (which might help builds for smaller devices look better, seeing as they're left with the cm10 one). You can cherry-pick this to cm-10.1, just thought I'd pull request here as I couldn't build 4.2 for some reason and its not as messy here.
