Delayed block penalization and new reward percentages (dashpay#66)
* Delayed block penalization (dashpay#62) - Delayed block penalization - Reset regtest - Change protocol version - Update blockdelay RPC test. - Fix min chain work on regtest chain params. - Add chain penalization field to getchaintips method. - Fix log formating * New reward percentages 70215 (dashpay#63) Changing the reward percentages, miners now get 15% and masternodes get 65%. * Change activation block height for new rewards * Bump min protocol and new checkpoint (dashpay#65) - Min protocol version is now 70215 - Bumped the version on the masternode update scripts. - Added a checkpoint, block `#216000`.
