Merge bitcoin-core/gui#740: Show own outputs on PSBT signing window

4da243ba02 qt: show own outputs on PSBT signing window (Hernan Marino)

Pull request description:

  This fixes https://github.com/bitcoin-core/gui/issues/732 .
  It allows you to identify your own addresses in the outputs of a transaction in the PSBT signing window. This enables easy identification of change outputs, and prevents certain attacks where someone (co-signers of a multisig, or others ) might trick you into signing a transaction while they are stealing the change, since prior to this modification there was no easy way of knowing this.

  The identification of the output is similar to the way this is done in the transaction details window.

  A sample output is :
