fix for ghost memory leaks

- ghost data wasn't being freed (added wm_ghost_exit() call to wm_init_exit.c)
- GHOST_EventManager wasn't freeing GHOST_IEventConsumer's
- ghost/X11 wasnt calling XCloseDisplay(), some junk from X11 wasnt being freed
- ghost/X11 XAllocNamedColor wasn't freeing the colors when done making a custom cursor.
