Fork of Go Ethereum

To setup make sure you install Go so you can run: make geth

This builds geth to the following location: build/bin/geth (copy geth from here to the private node)

This fork does the following.

1. Removes the "difficulty bomb". (This is a private network so we don't want the difficulty bomb)
2. Changes the time per second difficulty calc to be 1 block per second.
3. Mining gets 0 Ether. (All ether is granted at block creation to a central bank address. This moves to accounts as people deposit and withdraw dollars)
