This implements 1b & 1c of EIP150 by adding a new GasTable which must be returned from the RuleSet config method. This table is used to determine the gas prices for the current epoch. Please note that when the CreateBySuicide gas price is set it is assumed that we're in the new epoch phase. In addition this PR will serve as temporary basis while refactorisation in being done in the EVM64 PR, which will substentially overhaul the gas price code.
