dwm uses XGetClassHint() to retrieve the class and instance, and you
can't get WM_WINDOW_ROLE like this, so it's not as trivial to add on.

I've attached a patch (with some dodgy casting) that works for me, but
it's pretty useless. To have rules work with lots of arbitary WM_*
rules would mean extending the code a lot for little gain - Iron
(chromium clone) doesn't set WM_WINDOW_ROLE, for example, and nor does
surf, nor vimprobable.
