This PR ports simple_casper_tester to use tester2 from Pyethereum state_revamp.

This PR requires the changes to tester2 proposed in ethereum/pyethereum#717

Changes

  • simple_casper.v.py now checks for blockhashes before awarding rewards.
  • Includes the one-line fix added in Fix bug: not subtracting entire validator_deposit #10
  • Adds helper functions epoch_blockhash() and mine_and_init_epochs()
  • Adds a test checking if the rewards are actually given after a prepare & after a commit.
  • Turns the init sequence into a function which is called twice, once for each series of tests. This will likely be replaced by a function inside of casper_utils.py in pyethereum. However, there were some organizational issues I faced when trying to include it there, and so I'm holding off for now. This is a pretty simple change which shouldn't add too much to the code complexity.

* Add mine_and_init_epoch()
* Add epoch_blockhash() for getting the blockhash at a specific epoch
* Change t.k0 to just k0
* Change a few tests to pass
*Turn the Casper chain setup into a method to allow it to be reused when
initializing the chain during test 2
*Port second round of tests
*Change tester2 to raise TransactionFailed() if a tx doesn't go through. This
allows us to distinguish between a contract returning False and a tx exception
*Remove a few unneeded t.mine() statements
