Youtube - Revert Layout

This script will (hopefully) revert the current gross UI/layout Youtube has implemented (for some reason) back to something that resembles the old layout. Also, if something breaks, good ol' F5 might help. PLEASE NOTE: I'm updating this for my own use on Youtube and am sharing it as is. I will not be taking feature requests. There will be bugs and things will break and I may at any time choose to stop updating it entirely.
