family_signoff action no longer does use one-time ticket.

A note:
Now create_list, create_automatic_list & update_automatic_list Request handlers won't take "listname" as an top-level parameter, but it must be included in an item of "parameters" parameter.

Fix #634

- Currently, only light export is available, thus export doesn’t contain
  the name of the subscribers. The button solves that.
- The full export always includes a header:
  # Exported subscribers with search filter ""
  But it’s useless and maybe confusing when you use the full export from
  the button. I removed that header if no filter was sent.

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.

Replace Sympa::List::load_list_of_scenarios() with Sympa::Scenario::get_scenarios().

This will fix several bugs due to confusion with function and parameter.

[feature] New parameter shared_feature in sympa.conf/robot.conf to enable/disable the feature of shared document repository.

[change] Data sources: outdated users will be expired only when all data sources of the list has succeeded inclusion.
By this change, if there are data sources with nosync_time_ranges set, deletion of outdated users can be delayed 24 hours at most.
[change] Database schema: included_* and include_sources_* in subscriber_table and admin_table were deprecated.  inclusion_* fields will be used instead.

Fixed by getting recent owners/moderators passing cache.
