Check _MOTIF_WM_HINTS when attempting to manage an X window

Browse source 
* exwm-core.el: New buffer-local variable exwm--mwm-hints.
* exwm-manage.el: New variable exwm--atom-_MOTIF_WM_HINTS for holding the
  value of _MOTIF_WM_HINTS atom; new function exwm--update-mwm-hints for
  updating the _MOTIF_WM_HINTS property of an X window.
* exwm-manage.el (exwm-manage--init): Intern the _MOTIF_WM_HINTS atom.
* exwm-manage.el (exwm-manage--manage-window): Avoid managing windows
  without decoration (implied by _MOTIF_WM_HINTS).
