Introduce vpour to CTransaction.

Browse Source 
Transactions of version 2 and above contain a `vpour` field which is a vector of `CPourTx`
objects that embody our protocol. We introduce serialization primitives for boost::array
(we intend for changing the amount of inputs and outputs in the circuit to be simple).

SIGHASH_* operations hash this field like any other for now.
