Display change output and fee data when decoding tx hex for signing

[B0BSmiths]

It is ace users can now see the Counterparty data when signing txhex but could you please also show the change output and the fees, so the user can be sure the tx they are signing is not doing anything malicious

Added support for displaying change address and amount in commit abdc9c1

Next freewallet release will display change address and amount.

Adding support for displaying fee information will require a bit more work, and will be included in a future release.
