Peony collateral update to 10K

Peony (PNY) has a collateral update at block 630.000. The previous collateral was 5.000 PNY and the new collateral is 10.000 PNY. As usual we already created the new masternodes. All users that are still in the 5K ones, should cancel their slots and move to the new ones.

All Simple Masternode users must redo their masternodes.
