* [NOD-237] Implemented transaction mass. * [NOD-237] Added transaction mass validation to the mempool. * [NOD-237] Made blockMaxMassMax not rely on MaxBlockPayload. * [NOD-237] Added comments describing the new constants in validate.go. * [NOD-237] Changed the default blockmaxmass to 10,000,000. * [NOD-237] Fixed a comment that erroneously didn't refer to mass. * [NOD-237] Added comments to ValidateTxMass and CalcTxMass. * [NOD-237] Renamed "size" to "byte". Made validateBlockMass exit early if validation fails. Fixed unit names in comments. In CalcTxMass, moved summing of mass to the bottom of the function. * [NOD-237] Instead of ErrMassTooHigh, renamed ErrBlockTooBig and ErrTxTooBig. Replaced wire.MaxBlockPayload with MaxMassPerBlock. * [NOD-237] Fixed sanity checks related to block size in commands. * [NOD-237] To use up less memory during testing, made the mass in the "too big" test come from pkScripts rather than input bytes. * [NOD-237] Added an overflow check to validateBlockMass.
