NEP-01: State Blocks

The implementation of state blocks (known as "universal blocks") is a protocol improvement that encodes all account data in every transaction. This allows the following:

1. Simplifies account balance computation and block verification
2. Enables inexpensive hardware to easily and securely sign transactions
3. Aggressive pruning of the block-lattice
