move Amarok::ToolBar into a file of it's own.  split the toolbar into two separate classes, the basic toolbar just removes the border, the pretty toolbar is the one we use on the top (at least for now).  Use the basic Amarok::ToolBar as a base for Browser::ToolBar, which makes the browsers look much smoother.
