Reduced the overhead caused by all the diffirent implementations of the vm.Environment interface. Where previously the Environment was an interface it has now become an implementation it self using several new easy to implement interfaces such as the Backend that takes care of the state and CallContext which takes care of the EVM calling conventions. Most of these interfaces have been implemented in the core package with the exception of the test suit which uses a combination of the core package implementations and a mix of its own. This will reduce the amount of extra overhead when changing an interface, such as adding a new method or changing a method signature.
