+      Added the "forwardTransferScFee" and "mainchainBackwardTransferRequestScFee" data members to the certificate classes (both mutable and not mutable). Added a unit test to check that the new members affect the computation of the certificate data hash. Fixed some unit tests that stopped working after the changes.
+      Refactoring of the CSidechain class: removed "lastTopQualityCertDataHash" and "pastEpochTopQualityCertDataHash", now this value is included inside the struct CScCertificateView (which additionally stores the Forward Transfer Sidechain Fee and the Mainchain Backward Transfer Request Sidechain Fee).
+      Added the data member "mainchainBackwardTransferRequestDataLength" to the CSidechain class.
