Handle client messages for modifying _NET_WM_STATE_SKIP_PAGER and _NET_WM_STATE_SKIP_TASKBAR on mapped windows: Update the window property and broadcast the change for modules.
Both are mapped to the single skip-window-list property, so handling both client messages does exactly the same. A client trying to enable one and disable the other one will get the result of the last client message sent.
