- speed up UI navigation

Whoever was responsible for this patch, thank you very much! Before this release, cycling backgrounds on home screen items stuttered sometimes and wasn't nearly as fluid as transitions in media views (each home item is a folder of images, one is randomly selected when you highlight a menu item). After upgrading to this build, the home screen doesn't fade to black between animations anymore and media view transitions are even smoother when mashing the arrow keys to jump far down a list.

Every time I think the Pi has hit a new high you guys manage to do it again. Cheers!
