Removed feast hall items from inventory quest.

To prevent players bugging admin to open feast hall/reset the quest, I've changed the feast hall items from inventory quest for more easily obtainable items. Changed the number of waterskins as 70 waterskin = 2100 weight which was a little extreme.

In anticipation of criticism, yes grapes and goblets could be added to NPCs and that was a close runner up to this solution. IMO this solution still creates a challenge (finding the new items required) while preserving the uniqueness of feast hall food/not requiring create food mules.
