D16F: Set out the quest's things for a new game
Used by the routine at START.
Copies the eighteen records of QUEST_START to QUEST_RECORDS, and then puts the five collectables (records 4 to 8) in five consecutive places from SPOTS, the first chosen by the random number from the first sixteen: each gets its room, U, V and Z from its place. Called by START once the start tune has played.
