Subject: If _NET_WM_DESKTOP is set to -1 during client creation, place the
 client into group 0 (nogroup); solves problem initially discovered by
 oga@nicotinebsd with tint2.  A clientmessage *after* client creation already
 handles this case.

Go further and assign every client to a group; in non-sticky mode, group 0
(nogroup) and sticky mode, the active group.  In both cases, autogroup will
override the group assignment.  Removing a group from a client always places
the client back into group 0 (nogroup).  Autogroup can also assign a client to
group 0 (nogroup) to keep a client always visible (unless of course one opts to
hide all clients).
