GUI: Separate output selection and transaction finalization.
- Output selection belongs in the Send tab.
- Tx finalization is performed in a confirmation dialog
(ConfirmTxDialog or PreviewTxDialog)
- the fee slider is shown in the confirmation dialog
- coin control works by selecting items in the coins tab
- user can save invoices and pay them later
- ConfirmTxDialog is used when opening channels and sweeping keys
