[Xmonad] darcs patch: add WorkspaceDir, which sets the current directory in ...

This is pretty handy. And it's a resend that's been amend-recorded to eliminate some debug tracing. David Mon Jun 11 08:40:41 PDT 2007 David Roundy * add WorkspaceDir, which sets the current directory in a workspace. Actually, it sets the current directory in a layout, since there's no way I know of to attach a behavior to a workspace. This means that any terminals (or other programs) pulled up in that workspace (with that layout) will execute in that working directory. Sort of handy, I think.
