Merge rust-bitcoin/rust-bitcoin#1811: Use Amount type for TxOut value field 

d57ec019d5 Use Amount type for TxOut value field (yancy)

Pull request description:

  Propose using `Amount` type for the `TxOut` `value` field.  I only implemented `Decodable ` and `Encodable` enough to compile but this needs to completed obviously if using `Amount` seems like a good idea.
