I don't mess with _NET_CLIENT_LIST, it still reports all windows.

If you have two monitors, and they're pointing at workspaces 1 and 2,
with 1 being active and 2 merely visible, my patch reports the windows
on 1 as belonging to workspace 1 (the active workspace) and the windows
on 2 as belonging to workspace 2.

The previous behaviour had all visible windows (those from both 1 and 2)
reported as being on workspace 1, so that they'd all be on the active
workspace (since EWMH has no concept of two workspaces being visible at
once)
