	This should make it more intuitive to add new elements to the compose box (such as banners), and it also makes it a bit more clear for styling purposes that the same geometry happens whether the compose box is open or the buttons are visible. I lifted the #compose_container div into the server template. It's not totally clear to me why we need both #compose and #compose_container, but there are some scary comments about 1400px that made me too timid to address that quirk. In passing I removed a clearly redundant click handler.
