Bug fix #68: Second attempt to fix client window detection 

- Attempt to fix client window detection when WM_STATE property is not
  yet set when the window is mapped. Thanks to kinclma1 for reporting.

- Apply stricter checks for whether window is mapped in
  determine_evmask() and win_mark_client().
