  -----------
  gui2 mp create improvements

this fixes multiple issues
1) the game crashes if 'random maps' were selected if no user maps are
present becasue the level_types_ was not in sync with the correspading
combobox.
2) mp create gave a 'no sides in scenario' error when started first.
3) Unused config_eng parmaeter
4) create_engine_.prepare_for_new_level() having no effect becasue the
previous scenario was still present

5)The gui2 mp create now shows when experimental mp lobby is selected in
preferences (makes testing easier).
