Subject: [PATCH] fancybar, shows the titles of all visible windows in the 
 status bar

Inspired by the decorated tabbed layout of Xmonad this patch provides a status bar that shows
the titles of all visible windows (as opposed to showing just the selected one). When the
titles don't completely fit, they're cropped. The title of the selected window is inverted.
