Current questions and answers regarding the map editor.

1) I didn't understand. The script name applies to the hut itself, while the quest name applies to the quest.
2) You can do it like this:

function NewDay()
	if GetDate(MONTH) == 25 and GetDate(WEEK) == 1 and GetDate(DAY_OF_WEEK) == 1 then
		CreateMonster("monster_name", monster_type, number_of_creatures, x, y, floor, mood, courage, rotation_angle, height)
		SetObjectiveState('quest_name', OBJECTIVE_ACTIVE)
		startThread(killDemon)
	end
end

function killDemon()
	while 1 do
		if not IsObjectExists("monster_name") then
			SetObjectiveState("quest_name", OBJECTIVE_COMPLETED)
			break
		end
		sleep(10)
	end 
end

Trigger(NEW_DAY_TRIGGER, "NewDay")

The quest should be OBJECTIVE_KIND_MANUAL, and the IsInitialyActive and IsInitialyVisible parameters should be false.

And the animations are:
normal state, death, close-range attack, joy, taking a hit, shooting, spellcasting, special ability, panic (what creatures do in battle when you hover the cursor over them).
