Create On-Chain Executor

[johannbarbie]

The on-chain executor calls the initAndRun() method as transaction (needs to fit into block gas limit), but executes only 1 step:

• Have the EVM load at a given step of some program, execute the current OP-code, and return the state of the EVM (at next step).
• Implement unit tests for each OP-code in the following way:
  1. Run off-chain EVM and export state at steps x and x+1.
  2. Load on-chain EVM with step x, run 1 step, and compare with x+1 from off-chain.
  3. Implement tests where x falls on every possible Op-code (see list in architecture docs, except extra difficult).

This implementation will give us the confidence that the on-chain executor produces the same results as the off-chain executor.
