KC3改 Quest Class

Instantiatable class to represent a single Quest
Mainly used by QuestManager to store quest information

Quest Type:
1 = One time
2 = Daily
3 = Weekly
4 = Sink 3 Aircraft Carrier (only on dates ending in -3rd, -7th, or -0th) Bd4
5 = Sink Transport Fleet (only on dates ending in -2nd or -8th} Bd6
6 = Monthly
