sec: fix formatting
bigi: upgrade to 1.1.0
Transaction: remove TxIn/TxOut exports
Transaction: restrict TxIn input parameters

TransactionIn is only used by Transaction.prototype.addInput and the
Transaction constructor.
It is therefore safe to restrict these input parameters.
Transaction: use TxIn/TxOut consistently
Transaction: extract DEFAULT_SEQUENCE constant
Transaction: move all constants to top
Transaction: remove hash:index notation
Transaction: remove TxIn/TxOut from API
Transaction: add support for custom output scripts
Transaction: renames getHash to getId

Also removes the inherent calculation of tx.hash after a
deserialization.
If a user wants this, they can do it themselves very easily; the
bitcoinjs policy thus far has been to avoid result caching in the
default case.
Especially since a hash is not guaranteed to be the same if the
Transaction is modified after deserialization.

Also adds a test for getId.
