Set properties to work better under metacity, per the extended window

manager hints spec:
1) Set _NET_WM_WINDOW_TYPE to _NET_WM_WINDOW_TYPE_UTILITY, so that
metacity does not add zephyrgram windows to the task list.
2) Set _NET_WM_DESKTOP property to 0xFFFFFFFF by default, so that
zephyrgram windws appear on all workspaces.  Add the "allDesktops"
resource allowing users to override this behavior.
