			After moving the savegame code to savegame.cpp, there need to be a lot more parameters to pass to the

			the dialog:

			game_savegame save(gamestate, level, gui, teams, units, gamestatus, map, game_preferences::compress_saves());
			save.save_game_interactive(gui, "Save game", gui::OK_CANCEL, false, false);

			This code however does not compile anymore:

			BOOST_CHECK_EQUAL(dialogs::get_save_name_oos(test_utils::get_fake_display(1024, 768),
					"Save game?", "file", &fname,gui::OK_CANCEL, "Save game"), 0);
