Now that sending transactions works, it was time to rewrite the GUI
representation of a transaction to be general enough for more than just
one transaction type.
Still need to set expiration, so none of the transactions I broadcast
work yet... :( Sadly there is no testnet so I can't finish this. Oh well.
I'm sure it'll be much easier on Monday.
- Refactor GUI with FormBase.qml
- Fix memo handling in TransferOperation
- Add TransactionConfirmationForm.qml which will eventually display a
transaction for confirmation
