Support superior change rename

It requires net-ldap 0.5.0 (it is not released yet for now) or JNDI
adapter. ruby-ldap doesn't support it.

GitHub: fixes #56

Reported by Jean-François Rioux. Thanks!!!
Support superior change rename with ruby-ldap

I found that unreleased ruby-ldap (0.9.13) supports superior change
rename. So I use it if ruby-ldap supports it.
Add 4.0.1 entry
Use Packnga
travis: use mailing list address
Fix Japanese page path
Support net-ldap 0.5.0

It returns Net::LDAP::PDU as operation result.
doc: follow Packnga spec
adapter ldap: use rename only if new_superior is specified

Because ruby-ldap 0.9.14 doesn't accept nil as new_superior. If the
following pull request is merged and new ruby-ldap is released, we
revert this change:
  https://github.com/alexey-chebotar/ruby-ldap/pull/25
Revert "adapter ldap: use rename only if new_superior is specified"

This reverts commit ad22a771b2e7635ede7e76bb0e91e7fe75e7ac0a.

Because ruby-ldap merges my pull request and release a new version!
Awesome!!! https://github.com/alexey-chebotar/ruby-ldap/pull/25
