Line up ALL the things:

* Make folded adminmenu icons line up with the W icon in the toolbar
* Make the W link in the toolbar the same width as the folded adminmenu
* Reduce padding on toolbar links to match reduced padding between W and Globe icons
* Reduce right-side padding on toolbar links to account for 1px of extra padding around icons on the left
