dkim_sign: Normalize CRLF->LF for DKIM-Signature

ARC: Comment in Authentication-Results field prevents check on srvid (See #575)

See https://rt.cpan.org/Public/Bug/Display.html?id=129066

Slight change in list admins cache expiry.

Fix #548 — Add DB log entry when message is rejected or distributed via email

Mail::DKIM::Signer wraps DKIM-Signature with with \r\n\t; this
is the hardcoded Separator passed to Mail::DKIM::TextWrap via
Mail::DKIM::KeyValueList. MIME::Tools on the other hand
(MIME::Head::stringify() in particular) encode EOL as plain \n;
it is thus necessary to normalize CRLF->LF for DKIM-Signature to
avoid confusing the mail agent.

Fixed by parsing the field according to standards.

When changing a list's admin two times in the same second, the list admins cache is not updated. Consequently, when trying to add a third admin in the same second, the second one is not in the cache at the time.
Obviously it does not sound like a recurrent scenario and I met this problem when running a test file only.
However, it is possible that this happens more often when trying to make batch modifications in the shell. And also, it made my test fail which is an engineering problem: it could be misguiding about the cause of a test failure.
So I changed the expiration test, replacing "<" by "<=" and it solves the problem.
I don't see any side problem that could result from this change bu I commit it separately anyway because the cache is very sensitive.

WWSympa: TLS client authentication: Get email from certificate according to S/MIME

- 4 spaces indentation
- Indent on HTML tags AND on TT2 stuff ([% IF … %])
- Avoid HTML or TT2 oneliners like:
```
  [% IF top_menu %]…[% END %]
  <div class="displayNone"><a href="#top">Top of Page</a></div>
```
- When a tag has too many attributes to be on one line, indent the
  attributes at the same level than the first one:
```
<label class="foo"
       id="bar">
    Baz
</label>
```

WWSympa: TLS client authentication: Now it gets rfc822Name in X.509v3 subjectAltName, otherwise emailAddress attribute in subject DN (the first one of either).

Note: Earlier efforts getting attribute such as MAIL, Email in subject DN are no longer supported.
