1. Add a short paragraph on P2WSH (the witness script is omitted for brevity in all descriptions) and fix witness scripts for spending the different tx outputs.
2. use CHECK(MULTI)SIG instead of CHECK(MULTI)SIGVERIFY
3. Fix order and nulldummy for witness in HTLC transactions
4. Fix a minor typo (if -> it)

This lets us gain 7 more bits, but also as Christian points out, you need
to remember the padding for re-broadcast since the signature covers it.

We need to supply a pair (a signature using our bitcoin key which signs the
node id, and a signature using our node key which signs the announce message),
and the length was wrong. Move them to make alignment nicer, too (though
it probably doesn't matter, they're 4-byte aligned everywhere else).

This means they cover future fields as well (which may or may not be good!)
but also ensures they're naturally aligned in case anyone cares.

And make it channel-index not channel_index to match the others (markdown
doesn't treat - specially, unlike _).

Make the fee amount by kiloweight, not by kilobyte, and spell out how
to calculate it. Note that we have to trim HTLCs outputs whose second-stage
would also fall below dust limit, and we also make some reasonable
approximations on transaction size (which is unknowable before signatures
anyway).

The fact that a revocation response also serves to acknowledge the
pending changes (and thus indicate the sender should apply them
to itself) is documented in the desciption, but still terribly
subtle. Joseph suggested making it clearer, I think this
does that.

After much discussion with Tadge and Laolu, I think we have something
which is nicely outsourcable, and yetnot insanely complex.

This commit modifies BOLT 3 slightly to use a code block for the multi-sig script. Without this change, the script doesn't display correctly, as the angle brackets are interpreted as markdown syntax.
Calculations are put in 05-onchain.md, and referred to by 02-peer-protocol.
The number is 600, comfortably under the 626 theoretical limit.
