Subject: [PATCH] Guard WINGs realizeWindow against NULL display in Wayland
 mode

When a menu entry triggers a WINGs dialog (e.g. 'Run...'), the
realizeObserver notification calls realizeWindow which does X11 calls
(XSetClassHint, XAllocWMHints). In Wayland mode scr->display is NULL,
causing a segfault. Skip the entire function when display is NULL.
