Add Hunts to Challenge Log

[Antonio_Xul]

Since hunts have died down somewhat, how about adding them to the Challenge Log. Something like:

Kill 10 B ranks - 1000 Gil
Kill 20 B ranks - 1000 Gil
Kill 5 A ranks - 1000 Gil
Kill 10 A ranks - 2000 Gil
Kill 2 S ranks - 4000 Gil
Kill 5 S ranks - 5000 Gil

Also maybe add like a bonus for completing all 5 of the Daily Hunts, like adding tomes or 10,000 gil. Give a little more purpose to the hunts since not many people care about them anymore.
