All flying pigs to give 2xp as a reward for capturing it

The amount of time given as the reward could vary by piggy, and could range from say 5 minutes to 1 hour in the same way that the amount of cp varies by piggy so for example, the amounts given could be 5mins, 10 mins, 20 mins, 30 mins and 1 hour (or possibly longer amounts of time given for each level of reward, with the max being longer than the 1 hour currently awarded in some)
