Fix #533 — Prevent the use of the list address as subscriber

[ldidry]

In #533, I originally wanted to prevent adding the list address as subscriber with a reception mode which sends mail to the subscriber but:

• it’s far more easy to just prevint adding the list address as subscriber
• it would need to prevent changing the reception mode after subscribing, so more work
• I can’t see a usecase where you want to subscribe with the address of the list. But I think it’s better to have a backend check to prevent it (to avoid typo and other user mistakes)

po/sympa/sympa.pot needs to be updated as I introduce a new localized string. Shoud I run make -C po/sympa sympa.pot-update and commit po/sympa/sympa.pot or is there another workflow for that?

I documented the procedure to release new source tarball: See "How to prepare a new source tarball". As it includes a step to update sympa.pot etc., any beta releases may contain the latest catalogs.

Thank you. I updated the wiki

I feel the codes for error handling in add.pm & subscribe.pm are redundant.

We'd be better to insert

push @$stash_ref, ['user', 'email_is_the_list', {email => $who}];

before the next line above and withdraw the changes below in add.pm & subscribe.pm.
