[Xmonad] darcs patch: make mosaic configure windows by name rather than by W...

Here's a bit of a crude hack to make the window configurations depend on the names of windows. It makes mosaic just a bit more useful, when you open and close windows. David Sat May 12 14:56:44 PDT 2007 David Roundy * make mosaic configure windows by name rather than by Window. Note that this is still pretty flawed. Often window names change, and the layout then stagnates a bit. Gimp, for example, opens most its windows with the same name before renaming them, so you have to hit mod-return or something to force a doLayout. Also, gimp still overrides xmonad regarding the size of its main window. :(
