oga e75ea3304d One of the most annoying things to do was restart cwm and lose all of
your group state. Fix this up by using an X Atom (_CWM_GRP) to store the
name of the group that we're using (the name, not the number is because
at one point we may make the group numbers dynamic). I've been talking
about this since c2k8. so CM-w means you keep all of your windows grouped
properly.
