this check to decide if a group is virtually empty. Rationale: if a
group contains *only* 'sticky' clients, it should be skipped while
cycling through groups. Apply similar logic to the group menu.
Based on an idea from phessler@, who also tested another version.
to having to manage an array outside in screen_ctx for group names and
shortcuts. Simplifies (and moves bits for) reading, and constructing
data for, EWMH's _NET_DESKTOP_NAMES.
client to 'stick' to all desktops (ewmh speak) or groups - this
currently has the same affect as setting a client's group to 'nogroup',
with the exception that the client can also be in a group, so when
un-sticking, the client will go back to its original group/desktop.
group_show() and group_hide() are not the only ways a group can change
state - if all clients in a group are either hidden or unhidden, then
that group's state should change, as well as the various EWMH ways.
Instead of trying to keep track in a wide variety of places, simply
query the clients in a group before needing to take action based on the
group's state. Solves long standing confusion of when a group is hidden
or not.
symantics between cwm groups and ewmh got in the way. Ensure a client
that wants to be in nogroup stays in nogroup (thus stays in view), even
when (re)reading NET_WM_DESKTOP. Paritially reverts patchset 644

revisited when NET_WM_STATE_STICKY hits cwm.
Reported by many; testing and ok phessler.
since nhidden wasn't incremented nor decremeted in all the right places,
thus confusing matters. We don't need to carry a count around, so just
use a local variable in the one place we need one to supply
XRestackWindows().
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).
event on the screen's root window, there's no need to pass down the
entire XButtonEvent event, at least to group_menu(), the only callback
which takes an argument at this point; instead use the already populated
screen.
