[Stendhal] completeing jef quest should set state "done;"+..

Could the quest state when jef's mom's quest is done, please be "done" or start with "done;" rather than the "flower_brought_to_jef;" or what it is - this is the standard way to say a quest is done and then you don't need a special isCompleted method. some other quests do something more complicated, but if possible "done" or starting with "done;" is better.

thank you!
