AttributeError: 'NoneType' object has no attribute 'has_expired'
```
In SendTab.broadcast_transaction.broadcast_thread, self.payto_e.payment_identifier was referenced -
but do_clear() has already cleared it by then.
E.g. consider SendTab.pay_onchain_dialog: it calls save_pending_invoice(), which calls do_clear(),
and later (in sign_done), it calls window.broadcast_or_show, which will call SendTab.broadcast_transaction().
As there might be multiple independent transaction dialogs open simultaneously, the single shared state
send_tab.payto_e.payment_identifier approach was problematic -- I think it is conceptually nicer to
pass around the payment_identifiers as needed, as done with this change.
However, this change is not a full proper fix, as it still somewhat relies on
send_tab.payto_e.payment_identifier (e.g. in pay_onchain_dialog). Hence, e.g. when using
the invoice_list context menu "Pay..." item, as payto_e.payment_identifier is not set,
payment_identifier will be None in broadcast_transaction.
but at least we handle PI being None gracefully -- before this change, broadcast_transaction
expected PI to be set, and it was never set to the correct thing (as do_clear() already ran by then):
depending on timing it was either None or a new empty PI. In the former case, producing the above
traceback and hard failing (not only for bip70 stuff!), and in the latter, silently ignoring the logic bug.
- show a QLineEdit by default, a QTextEdit only if paytomany is active.
paytomany is a rare use case, it should not interfer with regular
use (e.g. when a user inadvertently types enter).
- this also fixes the visual appearance if the payto line
- keep paytomany menu in sync with actual state
- in lnurl.py, make request methods async
- in Qt GUI, lnurl network requests no longer block the GUI thread
- but they still do in the kivy GUI
- "lightning address" (LUD-16) support is removed for now as the
email addresses are indistinguishable from openalias email addresses
(both protocols should have added and enforced a prefix, or similar,
to remove this kind of ambiguity -- now we would need to make a
network request just to identify what kind of ID we were given)
- add param to _check_text to toggle if network requests are allowed ("full check")
- every 0.5 sec, if the textedit has no focus, do full check
- on textChanged()
- detect if user copy-pasted by comparing current text against clipboard contents,
if so, do full check
- otherwise, do partial check
- on clicking ButtonsWidget btns (scan qr, paste, read file), do full check
To reproduce: enter "." to amount_e in Send tab; then click "Save".

- We need only two types: PR_TYPE_ONCHAIN and PR_TYPE_LN
- BIP70 is no longer a type, but an optional field in the dict
- Invoices in the wallet are indexed by a hash of their serialized list of outputs.
- Requests are still indexed by address, because we never generate Paytomany requests.
- Add 'clear_invoices' command to CLI
- Add 'save invoice' button to Qt
