        Fix for bug #352263
        * gui/gdmsetup.c: Created more verbose warnings when defaults.conf or
          custom.conf are missing before terminating. Also all the error
          messages are displayed using dialogs rather than stdout. This is
          especially useful when gdmsetup is run from within login mamaner as
          it doesn't leave users wondering why it didnt start-up. Also check if
          gdm daemon is running is made before check for config files. In such
          setup appropriate message is displayed rather than config file not
          found.
        * daemon/gdmconfig.c: Daemon will not start if main configuration file
          (defaults.conf) is missing
        * daemon/slave.c: gdmsetup will not be launched if coustom.conf config
          file is missing
