The commit that removed metacity-dialog added a global SIGCHLD handler that caused problems by (a) calling waitpid(-1) and thus breaking g_child_watch for everyone else, and (b) doing too much from a signal handler and sometimes causing deadlocks (bug 596200). This removes the global handler and has each zenity user create its own child watch to watch for exit. (It also fixes the window class of the zenity dialogs, so that meta_window_present_delete_dialog() will work again.)
