Enable AutoSave in Execute scripts

[grumpyinca]

At this writing, running Search, Seek & Trade in an Execute script (Tutor, Demo) does not automatically create AutoSave data.

A Dec 2 Slack conversation indicates that AutoSave may be manually invoked in an Execute script with:

change

actions: [
        search()
      ]

to

actions: [
        saveAutoSave(),
        search()
      ]

Once this is added to ActionDumper:

case SAVE_AUTO_SAVE:
    result = 'saveAutoSave()';
    break;
