! As promised, fixed menu icons to be inline blocks instead of floats. This allows proper mixing of icon + caption + arrow in sub-menus, without having one overlap the other. This was only tested in Chrome, so it might break on Firefox or IE or whatever. Please test for me. Also, the main menu padding is not optimal (spacing below root items) in some skins, needs more work. Pff... I hate all of that. Where can I draw the line between 'functional' and 'good-looking' menus..? (index.css)
