redeem htlcs:
...
- fix bug in lnsweep: lnwatcher transactions were indexed by prev_txid
- add test for breach remedy with unsettled htlcs
- add timeout option to lnpay, and replace DO_NOT_SETTLE with SETTLE_DELAY
so that we can read intermediate commitment tx in regtest

rework on_channel_closed in LNWorker:
...
- use detect_who_closed; this allows us to redeem to_remote of breach ctx
- do not redeem to_local of breach ctx, because it is redundant with lnwatcher
- rename a few methods

lnsweep: fix create_sweeptxs_for_their_just_revoked_ctx
...
in the case where an htlc is failed, it could happen
that we use the wrong list of htlcs to generate sweep
tx'es. we would use the pending list instead of the
committed list.
observed by sending 12300sat and then 123000sat,
the second payment fails and an AssertionError was
triggered cause the htlc output could not be found
in the ctx.
added some documentation to clarify the behaviour
of lnchan.included_htlcs.
