Implement:

Create Delegate, Create Redelegate, Create Undelegate, Withdraw Delegation Reward

1 - To delegate tokens to an account that account has to be a validator 2 - The process of designating an account as a validator is tedious; I am working out how to do that

[wildwilliam2]

I am working on also restructuring how the StdFee object is made for all the transactions

This might effect issue #50

Implementing more robust response checking, a la #43
