Changes on POD format for transition to Markdown by ikedas

At least with kramdown, a variant of Markdown, alters two hyphens (--) in the
text to an en dash: See <https://github.com/gettalong/kramdown/issues/472>.
To avoid it, use C<...> instead of B<...> etc in POD.

Refactoring alias manager: Obsolete alias_manager.pl by ikedas

[-bug] WWSympa: When a owner closes their list,they will be redirected to a page of original list and defined access. Fixed by redirecting them to home page if they are not a listmaster.

- When list is closed, list could be marked error_config. Fixed by checking owner only when list is open.
- When list is restored, long time is taken before owners/editors are restored.

[bug] Previously, the third parameter fed to external program was the value of ``host`` parameter of the list, not mail domain: If ``host`` parameter was not the same as domain name, external program could fail.
Fixed by feeding mail domain instead of ``host`` value. And added [% list.host %] template variable to use ``host`` value in template.
Note that ``host`` parameter may be deprecated in the future (See issue #43).

[bug] return_path address won't be checked if list_check_suffixes doesn't include it.

- If value of alias_manager parameter has full path of alias_manager.pl as value, Sympa::Aliases::Template module will be used instead of invoking alias_manager.pl.
- alias_manager.pl would be removed in the future.

Sympa::Admin was deprecated.
